JB4 G5 iso Not pulling strong

GTATX · 02-28-2013, 11:36 PM

Ok guys I was pulling close to 17psi easy and car was crazy strong with g4 board, I updated to g5 and with normal firmware i was still pulling strong but with iso my boost is down and trims maxing out. I am running about 5.5 gals of e85 with 93 and dci. I have no codes. Im gonna try more 2500-6500 rpm 3rd gear wots again and my all map afr for all rpms is set to 0.

Any other advise.

GTATX · 02-28-2013, 11:37 PM

I have bugged Terry a lot so community help is appreciated. Thx

you have very laggy boost, check your boost selonoids, doubt it is a boost leak since you are on target except in the beginning, your timing is also not great...what fuel are you using?

GTATX · 02-28-2013, 11:39 PM

My lag is set to 60 should I change it. And don't have leaks as g4 board runs strong.

lag setting should have nothing to do what your log is doing in the beginning, I bet your boost solenoids are weak....I had this happen when I was on the G4 board.

What's the fix and is it cheap.

wow? That surprises me, either you have some bad gas or something...your timing should be much better than it is. See how it is diving?

I would test them first, around $250.00 if you install them...easy as pie to install.

GTATX · 02-28-2013, 11:43 PM

Never had issue this issue since I switched to g5 iso

I would for sure email terry with this.

GTATX · 02-28-2013, 11:45 PM

Please guide me how to test. Plus can it be adaptation is not done yet as I just installed it today. First I was running straight g5 pulling strong but since iso having issues but no codes.

GTATX · 02-28-2013, 11:46 PM

I did he said just try more adaptation as trims maxing out note changes needed as car was running fine before. Thanks

n54gte · 02-28-2013, 11:52 PM

Raise your open fuel loop. You might need to lower e85 mix or upgrade lpfp or get the bms flash or meth

Did you do several 3rd gear WOT runs?

robc1976 · 03-01-2013, 12:04 AM

Here are some before after new selonoid logs, this wasa way back when I had the G4 with stock turbos

GTATX · 03-01-2013, 12:40 AM

ran like 6 logs changes settings so finally got better boost.

I changed the future use to 2 and then open loop to 75. got better boost.

if u notice half way in the log car went to limp mode and previous logs as well 29f2 code so the above changes helped.

Advise whatelse can make the car run better and if this looks better than the previous log. Thx

BEAR-AvHistory · 03-01-2013, 01:09 AM

Are you guessing at these settings or is Terry telling you what to set?

GTATX · 03-01-2013, 01:10 AM

Open loop setting per Terry's notes from n54 forum I'm following as I had the 29f2 code. I'm new to this please advise if u see something wrong. Thx

GTATX · 03-01-2013, 01:12 AM

With this last log I went to 135 mph without any codes.

n54gte · 03-01-2013, 01:16 AM

Too much e85. Trims are wayyy too high!

boostaholic786 · 03-01-2013, 02:25 AM

trims are to high for sure! try setting your open loop mapping to 80 or 85. I think this will change your logs and the car will run alot better

Trust me I went through this before I got the BMS flash. My car didnt like anything over 5.5 gallons of E85 without the BMS flash so I would only put in 5 gallons and that temporarily fixed the issue. But once I got the BMS flash I'm able to run ALOT more E85 with even still more room and im at about a 70/30 mix E85/93.
