First of all I'm the second owner of the car...


Sorry for another meth thread, but anyway I just picked up my Evo 9 (see mods in sig) and the meth kit wasn't working so I turned down the boost from 27psi to 25psi to be safe. I happened to look at the spark plugs and notice that they were fowled so I changed them. The meth kit works perfect now, but the car is running really rich. The original tune (I have the paperwork) was 27psi on 100% meth. My question is how to I temporarily fix it without damaging the motor till I have money for a retune? With the gain nob turned to 8 I've done one pull. It was in 3rd gear, the car didn't sputter, but the afrs' dropped to 10.0 at 20psi so I let out of it instead of full pedal all the way to 25psi. I've read a ton of the what's good for AFRs threads for using meth, but how do you fix it on the go till a tune? Is doing these tests and running really rich bad for my car? Please help :-( So frustrated...Just want to be able to drive the car fully..

 

Honestly I would have to recommend getting the car re-tuned before getting on it full throttle. It seems like the car is definitely on the rich side and if you keep getting on it like that, you will be washing down the cylinders with fuel.

Also for the time being, I would do a boost leak test to make all the piping and vacuum lines are secure.

 

I'm the second owner of the car, but I have the paperwork for the tune from AMS. If I give you the guys name who owned it when you tuned it is there anyway to bring up documents on what exactly the tune was?

 

Hey,

If you can PM me the name of the customer, then I can talk to Chris to see if he has that information for you.
