Glad to hear you're doing better on AFRs. You should still do some refined tuning whenever you get a chance just to make sure everything is on the up-and-up.

Not trying to steal this thread... Jan, just wanted to say it was great meeting you at MOTD this year. I won't be able to make it to the tuning session in DC next week, but I will definitely be working to make it to one whenever you are able to come around next.

 

 

Jesuuus... I have another problem now.. I have just put on the GP tune and the car is running 10s to 11s but today i just stepped on full throttle from 2nd to 6th gear the car was running perfectly 2nd 3rd 4th and 5th gear but when i changed to 6th gear at about 200km/h it leaned out and runned 14s afr.. What might be the problem now? Im starting to freak out..
Please help
Thanks in advance!

 

Are the injectors big enough for the tune and RPMs? 380 isn't that big for drag racing.

 

Did you do any testing as suggested earlier in the thread? Whats your fuel rail pressure? 380cc injectors run at more than 80% with a 15% pulley, so if your spinning an overall 19% reduction then theres no way your gonna fuel properly with those

 

Why did you downgrade to the GP tune from a custom tune?
The GP tune is basicly a JCW tune.....so stock...you have a custom car...had a custom tune from reading the thread....go back to the custom tune to get back to the proper AFR ratios for your set-up....just cuss it says GP does not mean it is better on a modified car....custom is always better if done right.

 

.....why mess it up...
Like I said above custom is better than jcw and you mod list will never work with a stock tune...even a gGP/jcw...not for long as you are finding out...lean=boom!!

 

Agreed. A custom tune will have to be done/redone at this point.
