I have an 88t ecu (which are supposed to run more timing under boost), a t3 stock boost, and an NA block.
So let me get this straight...
To get more power (to a certain extent of course), you advance the timing to a higher BTDC, right?
BUT, I'm looking to keep it from detonating on 87 octane, so I need to retard the timing to a lower number, right?
My hood says it should be 20 BTDC. My parts car said 15 btdc for a manual transmission, but i don't know what car that hood came off of, it's not original. The books I have (haynes/chilton, i even checked the 88 fsm found nothing) don't give stock numbers, just say to look at the hood sticker
A gentlemen on Zchat last night suggested I use something around 17. What do you suggest? I know all engines are different, but what would be a good concervative number? It's frigid here today, so I want to be plenty concervative so it won't detonate on a 99 degree day next summer...
I'm a bit confused on this and will be warming up the car and setting timing as soon as i get this ghetto exhaust on. Sorry for the newbish question, but I don't want to screw this one up...
