Re: Issue with t4m2

tunes dont just go bad if it started doing it after 3 months you should not have changed anything that just makes matters worse

Re: E4OD torque converter lockup datalogging

locking in 2nd is purely up to you it won't hurt anything, some people like the converter to lock in 2nd some don't

you can simply look at the tcc lock and tcc unlock functions to see when it should lock and unlock

Re: developing a plan

you'll have to dial the injectors in

nope you can leave fn035 alone for now when you get your fuel dialed in just do a wot pull from idle to redline and plug in the corrections

since your naturally aspirated perload will be 1.000 at wot when dialed in properly

Re: Cvaf1

you would need a nitrous tune and a non nitrous tune no you would have to jack up the table to be at a higher load than what the engine would reach n/a since your spraying n2o. So lets say the engine reaches .90 load at WOT you would have to kick that up to say 1.65 load or so to give the extra fuel...

Re: developing a plan

in saying the max maf clip is right around where your maf pegs ~2350 so you do not need to scale it. You will peg your maf before you hit the limit.

Its no big deal though if you want to scale just simply cut everything in half it doesnt make any difference.

Re: 460 Swap - stock ECU

the entire eec is just a computer box. Simply swap out the ecu for a v8 and snatch the engine harness with it.

Your gonna have to go through the engine harness anyway so its really not a big deal.
