I hear ya...there is a huge learning cure with the UPREV software but it is def more then capable to handle what ya got.

Just to clarify when your trims are reading *80* it means your fuel trims are to rich and it is actually pulling 20% fuel....likewise the opposite, when it is reading *120* it means your are running too lean and the ECU is adding 20% fuel to get the desired airfuels....

 

you sure your cam timing isnt moving at 2250?

I have an 03 G35 also, and the new Haltech firmware doesnt work on my car. Hopefully its just a bad box, but I wouldnt rush to get a haltech yet... seems to be 2003 year specific from the other people I have spoken with

 

Yes I am aware of this. This is what is so confusing about my lean spot - the A/F compensation is at 75 when the lean condition happens! That means that ECU is pulling so much fuel that it is causing lean condition. That doesn't make sense. It's like it is overcompensating way too much and can't correct quickly enough once it has gone too far. Like a runaway condition...which makes me think there is a faulty sensor.

 

i'm in for learning.

i'm having a heck of a time with my osiris right now also. GRD is tuning my car saturday but i still am in WW3 with this thing. I'm determined to learn how to make adjustments so i can do it myself if i need to later.

Tuning that SS box was cake compared to this. I guess with complexity comes difficulty in tuning.

 

^^^^ Binder...send me your ROM and i will take a look at it and see if i can help ya out a lil better till ya get to your dyno session...

 

I have to say, that's some top work by vince to go out of his way to help a person that isnt even a customer of his (correct me if im wrong)

 

Vince is awsome!

he helped me get a decent ROM on here to get me to chicago. He spent about 30 minutes on the phone giving me the heads up on how i should tune osiris. Probably the best info i've received yet.

If his shop wasn't 16+ hours away i'd definitely want him to tune my car.

Thank you very much vince!

 

I'm 10,000 miles away LOL

 

take your CAI off before you drive through the ocean......rumor going around that you'll hydrolock your engine if you have a CAI

 

^lol

Don't give up mx594. Think of it this way, if you can tune Uprev you can tune anything, lol!

 

Care to relay some of that information ?

What does your fuel compensation table look like? What are the highest/lowest numbers?

 

I bought a Haltech.

Goodbye Osiris, goodbye UTEC.

 

all 100's. I've been tuning on the maf table like vince said. By doing it that way looking at MAF voltage and a/f and tuning the maf i haven't yet had to adjust fuel comps. I'm sure for exact tuning i'll mess with them a little but they were all between 95-105 a/f compesations when driving so not much adjusting needed.

Read str8dum1's post about his firmware issues with an 03 ecu and haltech.

also, don't get rid of osiris, you'll need it to set your static values such as higher idle, higher rev limit, and removing speed limiter. Osiris does some helpful things. Just put the base "stock" osiris tune back on so you can adjust static values but have a stock osiris ROM.

 

I have been following str8dum1's issues so I am well aware of what he has been going through. However with that said he is only one of many people who run a Haltech and most people don't have any issues so I am not too worried about it.

Haltech can control rev limit. I am never going to hit the speed limiter anyway so that doesn't matter. The only reason it would be nice to have Osiris with the Haltech would be the ability to modify the electronic throttle control settings and target idle RPM. But I would rather sell it and get ~$500 than keep it just for those two reasons.

 

haltech can only ADD a revlimiter. You cannot use it to modify the stock rev limiter so if you flash back to stock ecu you can't rev over 6600 rpms no matter what. You have to raise that higher and then you can set whatever limit you want through haltech.

155 is speed limiter, i hit that with just an intake spacer. It didn't come quickly, but i got there.

Depending on your setup you might be ok. I know for a fact with my built engine and cams that the car will not idle at stock idle. It will barely stay running at 800rpms. Anything below 800rpms and it lopes and dies. 1000 seems to be the sweet spot. stock engine you could get away with stock idle but even then my old stock engine didn't like idling at stock when it was boosted.

I guess you could boost your idle with the cipher cable to around 850 before you got rid of the cable so that would help. You would be stuck with the 6600rpm rev limit though. I guess that wouldn't be an issue on a stock bottom end. More safety.

Your car your decisions, i was just bringing that to your attention so you didn't sell it then kick yourself later. Osiris does everything i need with my built block so i'm waiting to add a haltech to the car when i'm out of med school and have money to burn.

 

Points taken. Sure it is possible to hit the speed limiter (especially now!) but my point was that I am not reckless enough to do it on a public road. So that's a non issue. And my car has always idled just fine. I can see why your car doesn't like to idle with the parasitic drag of the supercharger and the bigger cams, neither of which I have to deal with.

I'm pretty sure the Haltech can change the rev limiter on 03 and 04 - heck even the UTEC can change the rev limiter. The rev limit is just a fuel cut so if the Haltech is in full control of fuel it should be able to define it's own rev limit.

 

mine idles bad even without the supercharger. I take the belt off when i drive distances and it acts just the same. mine just has to be bumped. You can do that with just hte cipher cable though so no issue there for you.

Email hal, just like i said he cannot adjust the stock rev limiter. You can only adjust that by adjusting the stock ecu through a flash. Once you raise that you can set a rev limiter anywhere you want. He uses a flash when tuning to change the static values (rev limit, idle) on the ecu even when the haltech is being used.

exactly from the manual:

5.4 Rev Limiter Settings
The ECU can provide a hard RPM limit. This RPM limit is not an adjustment on the factory ECU’s RPM limit.
This RPM limit is purely for engines not fitted with electronic throttle control.
Rev Limiter: This setting allows the Rev Limit to be switched on or off.
Rev Limit: Determines the RPM at which the RPM limit will be activated.
Cut Type: Determines how the Rev cut will be applied. This can either be through the cutting of Fuel or Ignition
Pulses.



but you can still sell your osiris tuner for 500$ then pay 300$ for a standard ecu flash to raise your stock rpm and increase your idle and you would still save 200$ total.

 

Interesting. I wonder then why the UTEC can change the rev limit? Again, doesn't really matter to me though because changing the rev limit on the stock block is probably asking for it...especially under boost!

 

ya, i do'nt mean to sound argumentative. I'm in finals week at med school so i'm on edge. My main point was i would hate to see you mis-informed and then have to get the car reflashed by someone after you sold your cable.

if you're still on stock block then just leave it, bump the idle with the cipher before you sell it, then when you switch to build block you can get a flash to up the rev limiter.



feel free to donate the haltech to me if you hate it.

post some info on your tuning process with it too. i'd like to know as much about it as possible since i'll be going haltech or pro efi 128 when i get out of med school

 

Haha no problem, I would be on edge too. I appreciate your concern
