So you did get it to work....what was the problem

 

CAN integration is for ProEFI use, not for end user usage -- CAN gauge/any external add-on's that the user may want to add.

Anything that ProEFI programs it to.

Fault Management is EXTENSIVE, and can be set to trigger off of any sensor(s) or condition(s) and can have MULTIPLE triggers, not just one. Example:

*If fuel pressure varies by more than 10%: Turn check engine light on, lower to base boost, activate rev-limiter.

It has it, and it's working You can control the pump if you have the hardware (and the tune, when the Meth kicks in). Actually, at Intense we've installed it on a number of VQ based cars already.

That's accurate.

Given that we here at Intense are very privileged to have Jason do the great majority of his r&d right here at Intense, we have first hand knowledge of his progress. To that end, I will continue to answer all ProEFI technical questions as long as they're not pointed/loaded.

Ask away

Darrrren(getting ProEFI 48 on his S14 Sr20det as we speak)

 

He went back to UTEC

 

im guessing reason would be the european influence in said region

i dont know a single carribean/west indian person named trevor, but i know lots of trevors including myself.

 

Reinstalled my Utec.

While doing that I also installed a Labonte Motorsports Meth kit.

Working 9-5 5 days a week doesn't give me as
much time as I would want to finish everything
but I should have her back on the street by the
end of the week crossing my fingers.

All I got left is to clean up the wiring,lock everything down
put everything back together.

Thats if the wife doesn't find some thing for me to fix
around the house or the kids don't have some activities I have to attend.

 

Oh I see. Let us know how it works out.

 

Thanks for the detailed reply Darren - sounds great. I was also wondering if the CAN gauge had a button or buttons for 2 way communication (like for triggering different maps/boost, etc) or to flip between channels being monitored?

I have 2 innovate XD16 gauges and they look and work great - and have a button on them that does absolutely nothing for me! I wish I could flip channels with them, but alas no. I actually have to rewire (terminate) and reprogram the gauges using a PC to change what channels they will display.

Last question for now - promise: how does the end user figure out what is wrong when the CEL is thrown? Do they have to get the car to a pro-tuner?

 

I already convinced myself...I own a ProEFI! You guys keep glossing over the features that ProEFI has that makes it unique and just discounting them as if they didn't matter. The problem with all aftermarket EFI has been no real fail safes. You make a mistake as a tuner, or have a $100 fuel pump go bad...and boom... buy another engine. There is nothing there to "watch your back" The ProEFI's back bone is failsafe's...things that keep your engine alive under any circumstances. I don't care how good you think the other systems are...they don't have these features. Telemetry isn't going to save you when your going down the front straight at full throttle and start losing fuel pressure. Maybe it's just me not being able to afford $8k to build a motor and have it installed because of some stupid little problem like fuel slosh, or having a vacum line come off the fuel pressure regulator, or one of the two fuel pumps in the tank die! The ProEFI can catch those issues 6 ways from sunday BEFORE the engine is lost. Apparenlty this isn't a consideration for you guys...you're all loaded and can afford the down time, and to spend $6k+ on a motec that will still allow your engine to blow up over a failed $100 part.

I dropped by Intense yesterday because I was in the area, and they had an R34 SKyline strapped down to the dyno... my curiosity peaked of course. They had just finished the install of a ProEFI to replace the Power FC that was in the car. This particular car was set up by XS engineering in CA, which everyone knows is a very reputable shop. The car was being switched over to the ProEFI. Apparently the customer who owns the car was interested in the ProEFI just because he wanted to add a two step for launching the car at the track. According to one of the guys at ProEFI he swore up and down they would NOT make any more power because the car was very highly tuned...which the owner was fine with. The baseline of the car on pump gas made 510rwhp at 1.68 bar (24.36 Psi). I arrived just in time for the first pull. The first pull was somewhere around 445hp at 14psi (base boost). The second pull, same boost, was 491, and was already dialed in for Full throttle redline pulls (8k rpm). The third pull the boost was turned up to 1.3 bar (18.85psi) and it made 522. The 4th pull, boost was set to 1.38 bar (20psi) and it made 544....at 4.3psi LESS boost, and in 4 pulls. They stopped there until they contacted the customer to see if he wanted them to keep going (apparently there is a problem with the stock oil pumps on the RB26). I asked them if they had done a skyline before because of how quickly the car dialed in, and he said....no, this is the prototype. He quickly pointed out that the basic engine layout was the same as a supra, so you just start there and tweak a couple of things. Made sense to me... I asked him how long it would take to dial in the light load and drivability, he said about 25 to 45 minutes with cool down, we now have the V.E. of the engine, so that goes pretty quick! I asked him how long it took to tune my G. He kind of laughed and said....one pull! They just put in the base map from the stock Z they did the developement on, so they just checked it, and it was right on the money as it should be. Maybe i'm simple, but that impresses me!

 

I'm intrested in the can gauge as well. http://www.proefi.com/productlist.php

It has an up and down button and a menu button. I know you will be able to make some on the fly changes with it like boost settings, high or low octane settings, but not sure how deep it will go. I like it for the multiple diplays purposes.

 

Who's everyone? I never heard anything about this. It does seem pretty obvious that you had other issues, which is too bad. To down grade from such a capable ecu to a Utech.... your experience must have been pretty bad. Looking at your plugs, it looks like you had some serious overfueling problems. What was your first tuners "opinion"?

 

1ZweetZ, you can set up failsafes on the other units. Knock retard, EGT feedback, AFR feedback, and temp sensors are all employed to regulate safe operation by the standalone. A creative builder/tuner could employ other failsafes if they spend the time to implement and dial these components in. There are also electronics out there dedicated to this stuff. It really comes down to what your trusted tuner decides is necessary. None of the standalones on the market are going to survive for long (Motec included) if motors keep blowing up under their care!!! It just doesn't happen - and a judicious consumer will look at the track record for an EMS, not a feature list to make an informed decision.

By your reports the ProEFI takes this up a notch and makes implementation of robust failsafes easier for a tuner, but even for the ProEFI, the builder/tuner needs to install sensors and dial in many of the features for them to work.

I personally think it's great to see improvements in product offerings since competition drives product quality up as a whole. I think its one of the reasons the FCON recently provided upgraded hardware at a lower price point. That's good for consumers! The fuel pressure failsafe as described by SnyperZ is nifty for sure and you can bet I'll be bugging Hal and Sharif to implement this the next time I take my car in.

 

I think he got a good deal for the ProEFI that it almost didn't cost him any $$$ and still gave it back means he really had enough of it.... ProEFI future look promising but for you to keep saying it stable and had gone to rigorous testing is not accurate... Let us wait until more users adapt it and start using all the features, and if it work flawless then we can all celebrate!!! You dont even have any FI yet and only have the EMS for only a few days (maybe a couple of weeks) and you are already a nuthugger.

 

Our definition of failsafes appear to be different. Engines blow up all the time under "the care" of all of these aftermarket ecu's, however it has become accepted in aftermarket performance that you will have failures...it's racing. However most of the failures I have seen could have been prevented. You do not have lean shut down procedures with the current aftermarket systems, you do not have low oil pressure threshold shut down procedures, you do not have active check engine lights that will tell you the problems and perform action.... You might be able to tie a relay in to your boost control and set up a table based upon pressure input to shut down boost under a certain condition... this is not anywhere close to the same thing, and would cost you a small fortune to pay your dealer to do. With the ProEFI, you simply go into the fault management screen and select the actions you want under certain conditions, and yes, you can set multiple actions for the same conditions...I.E. when oil pressure drops below a certain level at a certain rpm, turn on the CEL, SHut boost down, turn off nitrous, activate rev limiter, shut down engine. It's all definable.

 

I understand the benefits of failsafes, but it certainly is not the first unit to have it, nor is it the first unit to have an autotune function or a guide to setup the VE table (My TEC2 had this, back in the mid 90's, and the very simple LINK system I used in my STi swapped Subaru back in the late 90's had this as well). Will be curious to see how it works in the long term though, as I may end up looking to an upgraded ecu for my own car.

 

, do you have a video of the dyno?

 

You see one guy that had problems, I have personally seen over a dozen with zero problems. Forced induction has NOTHING to do with it. An engine is an engine...it either runs properly or it doesn't. I have experience with the ProEFI... doesn't matter if I have had it for an hour or a year, I still have one, and you do not. If your opinion is to wait until everyone else has it, that's fine. I'm discussing my experiences with it, I don't get commission if any one buys it. I suppose if I had negative things to say...you would be leaving me alone... not saying "well...you have only had it for a week...what do you know" like you are leaving Glex alone.... really doesn't make much sense does it? Wheather you like it or not is irrelevant, a lot of the other people on this board want to hear real world feedback.

 

Autotune and adaptive learning ARE NOT THE SAME THING. Boost cut and a revlimiter and not really failsafes, most people don't blow up their engine becuase they overreved it, and most people set up boost cut so that it is up out of the way becuase their controller spikes on the ramp up and it hits the cut all the time.

 

But you keep insisting that the ProEFI has all the features working and has been to rigorous testing!!!! 1 year is not enough testing, 4 test cars doesn't mean it will work flawless for the 10000 cars left out there. This is a new EMS and there are going to be updates and changes so for you to say that the EMS is ready to go for prime time is questionable. I'm pretty sure ProEFI will be a good ems down the road but there is still a big ????? ProEFI may have all the features in place but that doesn't mean it will work 100% for everyone, who know it may work 100% but we still don't know until most of them start using all the features to the fullest. For example, Utec released a feature that it will allow for it to control boost, the feature was there but shops went crazy on making it work. They had to release an update to fix it

Edit: there is a big difference between NA and FI since FI cars will use more feature that is available.

 

I didn't say aything about rev limiters or boost cuts. My TEC unit had all sorts of user-definable parameters we could setup to trigger safe modes, and the TEC 3 I now have I think has even more (I have not driven the car in about 3 years though, so going off memory). I've never had any issues with boost controllers causing any spikes on any of my own cars, but that's probably becase I took the time to use the right wastegate for the job in the first place.

I stated what my tuner had said in that thread.

1sweetz should not make suggestive posts that everyone who has had a Proefi has been thrilled with it, because that is clearly not the case, at least in my situation. And 2. Proefi selected their dealers/tuners, and the one designated to tune my car, obviously had issues with the system that ProEfi did not seem to care about. I was willing to drive 14 hours away to get a second opinion because of the limited ProEfi dealers in my area.

I dealt with the system for 6 months.
I tried being very patient and hoping we could make this work.
When 6 months has passed and not one rep would be willing to
take a trip and see why one their dealerships is having such a hard time
to get their system up n running that is a lack of utmost support.
