So this weekend we are all hanging out at a friends house we always go to (wld350z) and GurgenPB decided to put his EU in his Power Entreprise Twin Turbo G35 Sedan, with a built bottom end and return fuel system. So Gurgen and I tackle this job and about 4 hours later we are done wiring everything and installing the EU. After all that work we hook up the EU and start the car, next thing we know it dies!

After further diagnosis we find out the EU was bad. So we took the EU out of Wld350z's car (hehehe) and plug it into Gurgens since he has a 5 hr drive back to San Fran. this morning. After plugging in the good EU into the car last night it was perfect! we adjust some settings in the EU and loaded a base map he had previously created then i jumped in the drivers seat and with him in the passenger seat started doing some "road tuning"

We are using option 1 for the greddy pressure sensor and option 2 for a/f ratio input. We are using the Innovate LC-1 wideband (one of the best if not the best wideband out there).

I have to say the A/F targeting feature on this thing KICKS ***!!! We inputed in the A/F target map what we wanted the A/F to be across the board and we just drove and it dialed it all in, it was BEAUTIFUL!!! We ran very conservative timing at about 14 degrees across the board. So all we did was drive the car and it basically tuned itself as far as the AFR goes.

base boost on this car was 9psi, so after a while of driving we turned it up slowly to 12.5lbs. Man this car was INSANE! I have never driven such a fast 4dr sedan! He also has the SGP valvebody upgrade since his car is a A/T. It was ALOT of fun driving this machine. No i really cant wait until my car is finished!

But anyways. The EU has awesome data logging and interface, and when used with a high quality a/f meter it works flawlessly, once the stand alone timing feature is activated through firmware update it will be an awesome EMS.

Just wanted to let you guys know our opinions on the EU, and it is a really awesome unit for the price, it will be even better in the near future when all the firmware updates are done!

P.S. Thanks too Shariff @ Forged Internals for all his support!!!!

 

Glad to hear the good reveiw. I was actually wondering how well the target a/f worked. good to hear

 

What were your parameter settings(5.0% IPW max, 20ms, etc). I got to use it on a friends car and I was wondering why you wouldn't want it to update as fast as possible(20ms is the fastest I think) and have alot of room to move(5.0% IPW per event). It is a much easier thing to tune using it because you just put the values in the AF target map, make a couple runs and it adjusts, put those values(+ or -) what the stock is according to the log and go from there. It is also nice that it shows the timing the stock computer is trying to run. I'm taking out the old blue and puting in a EU when my sleeved block gets back. Glad to see Gurgen back on the road!!!

 

I could just imagine GurgenPB's reaction when the car died

 

Glad you are enjoying tuning the EU. The AF target map is a very useful, especially when starting from scratch, and trying to build some base maps. Best of luck.

 

Just seeing if my stupid a$$ understands you correctly..
Are you saying that starting from scratch, plug in your AF targets, make a few runs so it'll adjust and then go back and adjust your injector map accordingly?? Sorry if this is a stupid question..

I don't have an EU but trying to learn as much as I can in the event I do purchase one..

 

Pretty much. You see how much IPW the EU added or took away to get to that AF and you are done(for that boost level). This will get you real close and the EU will micromanage the IPW for changes in the air. Of course you want to load a conservative ignition retard before you do this and later adjust the ignition more aggressively.

 

With auto-tune mode, the EU will automatically build the injector map for you, based on the AF targets you input into the "Target AF map".

 

Gotcha...

 

Yup thats correct, this is truly and awesome unit for someone who wants to do their own tunning. Gurgen will probally chime into the thread later on with more technical data regarding your question theking.

 

xbs,

do you have any experience with the utec? if so, how do you feel it compares to the eu?

 

I have experience with both. While the EU has a great looking GUI while UTEC uses a no frills hyperterminal and has knock feedback. Also you offset the timing of the ECU instead of absolute values like the UTEC. Utec is like a UNIX machine that does things rock solid and very dependably while the EU is like a windows XP machine because it looks better doing it but can crash(ignition offset while the ECU tries to advance). Best parallel I can draw, lol. The UTEC has no AF feedback and that is pretty much the only thing the EU does a little better.

 

Hey Guys,

Yes, yesterday was quite a day; and this:
pretty much sums it up. But thank goodness Tony and George were there, as I was ready to kill somebody. My luck is truly something!

As far as the auto-tune is concerned, it is incredibly accurate and fast. I used 50 (or 100) ms response and te minimum correction of 0.5% IPW duty. The latter small value allows for very precise corrections. Without having tried it, I thought it would at least get us close enough and the rest would be done "by hand". Forget that! This thing got it right on the VERY FIRST RUN, probably owing to the relatively fast 50ms response time.

Also, I would say that as it stands TODAY, UTEC can do more. In the future, the difference will disappear when standalone timing is released. AFR auto-tune is EVERYTHING... A single boost setting tuning session is comprised of, well, simply driving the car! It is THAT accurate. The same would take MANY MANY RUNS on a dyno, followed by careful calculation and/or trial and error for setting every point on the map that needs correction (AFR that is).

I'm glad that I am back on the road!

 

It does I believe if you buy TXS's WB to datalog with it...I just found this out. Innovate WB wont work with the UTEC.

 

The more I read about the EU the more I like it.

 

Dataloggin of the EU is WAY better than datalogin in a utec. and its WAY faster to tune and learn. EU has speed two step, auto tune, great datalogin, etc.

 

what happens if the a/f sensor that is wired to the EU goes bad? I am not using the auto tune feature because I fear my sensor might go bad and read incorrect numbers. Since the EU will try to adjust on those numbers it could be ugly if you car is running leaner than what the sensor is reading. How do you prevent this? I would really like to use my auto feature to compensate for temp changes.

 

Let me flag this question.. Keep maps when the EU and Wide Band are O.K.

Wide Band takes a dump - No problem

Plug in the Saved maps and turn OFF the Target AFR. You should be good to go..

I'm sorry I had to leave this tuning session, as my fingers were gone numb...
I drove back to home, and had to take a hot shower to get feeling back...

Guess I'm getting old.

Cheers Amy -


As XBS George said = E-Manage Ultimate ROCKS! - Oh YES!

Actually - when you have a good map series - turn off the learn AFR - and all the Raw Power should be back...

I take it from Gurgen's post the trip back to SanFran was un-Eventful...

Where is the replacement for Wld350Z's - there is a show to get to next weekend.

Could plug-in an E-Manage Blue... If XBS hasn't sold the darn thing..

 

John,

hehe... The trip WAS uneventful...got here ok.

I am fedexing the EU back to Tony tomorrow. He will have it 10:30am Thursday morning, with HIS map back on the unit. So, all he has to do is plug it in.

The wheels are in motion to get a replacement for my defective EU. We'll see how soon that turns out to be.

And no, Tony cannot (and won't have to) use the EB with the current wiring. Not worth the effort.

Let me put your worries at ease. First of all, using good equipmen tlike the Innovate, and making sure it's wired correctly (common sense) makes failures extremely unlikely. Second, a wideband failure will not jsut occur in the middle of operaton. WB O2 sensors will fail, if they do (and this is more likely tp happen prematurely due to an incorrect sensor install), at startup. Third, you only need to use the auto-afr tune function during tuning, and not full time. While oyu are tuning, you'll be stairing at the datalogger screen, and it will obvious if your AFR is off (like, reading 7.6AFR, same as 0volts). If it is, just don't go into the predetermined range of 80%+ of throttle opening, and the AFR feedback is not even activated. There are MANY safeguards. The actual controller portion of the Innovate! LC-1 is all state-of-the art, solid state device, and is no more likely to fail than EU (or for that matter ANY EM device) itself; in fact, it's far less likely, as it's a significantly simpler device than an engine management solution.

Gurgen

 

Man I hope GReddy comes out with the stand alone timing input soon, cant wait. Once my car is done we will see how much power we can make with this thing, looks like im going to be doing alot of testing with my motor huh gurgen, rods, cams, etc.
