The LTFT are negative, -7 at idle and during a WOT pull they come closer to 0. Strangely when I was starting the car for the first time today, they were positive during some time like +4.

But I never saw them below -10.

Anyway, I did some WOT pull today and my car was fine.

We had a HEAVY rain 2 days ago and its possible that my car sucked a lot of water.

One thing I saw however is that my AFR is like I said earlier in the thread, down to 11.8 during a WOT pull in second gear, but in third gear they go down to 10.1 !!!!!!!!!!!

Its weird that I dont have the same AFR in third gear... maybe because the tune senses the IAT2 heat then make the AFR richer when I hit a certain amount of IAT2. Is this normal? My IAT2 climbed to 145F during the third gear pull. This is a hotter day.

I'm gonna install my new phenolic spacer during this evening

Tune is fuct.you need your maf tuned and you need some timing adjustments at the very least.

There is no Table for AFR adjustments related to IAT2. the ecu can only pull timing and boost in relation to high IAT2 temps. This isn't going to cause you to run THAT much richer.

So if I do a pull in 2nd and another one in 3rd gear, I should see the AFR reacting the same way... if it goes down to 11.8 in 2nd gear it should also go down to 11.8 in third gear... even the same thing in 4rd gear.

To make the story short, the AFR should be the same in all gear when I do a pull...

alright thanks for the help for both of us guys haha i will check out my LTFT in a min.

ionRL_585

ok so on the scan gauge would i be looking for long term bank 1 or long term bank 2? bank 1 is never near zero the closest it gets is -7 other than that its always -12 or higher crusing or at idle. bank 2 is -100 or something like that but it never changes.

am i on the right settings to read ltft? if so is it because my tune is already messed up? i have had this tune for only a couple months.

my car use to hesitate bad at wot around 7k but when vince redid my tune it went away.

ionRL_585

how is your car when you get into boost? mine is like a crack head in withdrawl.

ionRL_585

yeah ik i was suppost to get my tune touched up by one of vinces dealers "gdubs" on here but its a pain in the ass since we have different scheduals and now that i am at my new job. i think its time to man up and invest in a dealer cable soon. not that geoff isnt a good guy it just seems that this car will need ALOT of touching up everynow and then so it will avoid the hassle..or i just gotta buy/learn HPT.

wow it seems like a lot of users have their car "untuned" LOL like... the tune is too much off compared to what would be ideal...

Not too many round here speak that Canadian/French stuff.

man i havent took french in a while lol so it was pretty ass when my uncle came from france..yes thats right an asian frenchman!

but anyways from what i can make out he/she said..."did you figure out the problem? let me tell you that with the 2.8 pulley and gapped at .035 it threw a CEL [limp mode] yours didnt have a code? now on my 2.5 i am having some problems at .032."

something along those lines..its 4:20 am and i havent slept in days. doing all this urban exploring keeps you up.

but still no change on the status of my car. it seems to cut off even earlier now..damn it!

ionRL_585

ok now my ltft are in the positives it was around 18.7 at cruising at some points. i am meeting up with one of vinces dealers to get some logs recorded and hopefully its just the tune cause i am stumped!

you might have a vac leak...

Bah... j'ai toujours quelques problèmes. Le nouveau qui est apparu c'est après qu'il pleuve. Le char avale de l'eau facilement! Mais en me mettant un dryflow ca devrait aider le problème!

Sinon quand je fais une pousse en 3, mon AFR n'est défois pas le même qu'en 2 et quand je dis ce n'est pas le même, on parle de 10.5 au lieu de 11.8 là...

Mais mon LTFT est à chier et est très variable... défois -11, défois -3, en tout cas il est souvent loin de 0.

Sorry for the French people, it is almost 4 AM here and I'm tired as ****! I'll translate maybe later! Anyway there is Google Translation. I used some slang so maybe some words will not be well picked up by Google lol

i cant seem to find the damn thing. i think i do too cause i can hear a whistle that i never heard before. i replaced the IM gasket, TB Gasket, IM itself looked okay [no leaks]..now i noticed one bolt from the TB is missing and my maf is held in the intake by zip ties. would that cause any kind of issue?
