355 tpi with t5
Ok so i recently did a t5 conversion on my 88 firebird and im wondering if it is possible to get the tpi 350 to idle. Right now the idle on it is way to high 1100-1200 rpm exactly. Now i know i dont have a vac leak so im good there so my concern must be timing.
What is the correct way to set timing on the tpi setup. Wonder if i didnt do it right

Re: 355 tpi with t5
Ok so this is were i went wrong should i also bypass the aldl port this should help not having the ecm trying to fight with the advancing and retarding right ???? I'll give this a try and see if i can get it to idle somewhat decent ill be happy with a 800-900 idle

Re: 355 tpi with t5
did you change the chip? i believe the programmed idles are different due to the park/drive flag

Re: 355 tpi with t5
IDK what you mean by bypassing the ALDL and IDK what that would give you.

Re: 355 tpi with t5
Yup. The man. and auto use different bins, and it's bigger than just the Park/drive flag. There are TCC settings, logr/higr settings, tables that depend on these... the MAN. bin pretty much adjusts tables based strictly on RPM alone, as the man trans has no switch to tell the ecm what gear it's in. He'll want to change his prom to a prom for a manual.

Re: 355 tpi with t5
