2.3 stroker pointers

Postby 96 awd of the 808 » Fri Jan 08, 2010 2:29 am

Alright its time for me to take a vacation from work in two weeks, for 2 months. So now i get to put my baby back together. I'm going to stroke it and im looking for some tuning pointers to think about. Its just the traditional 100mm crank 20 over pistons fully balanced.... My stock ecu is chiped for 850cc injectors and 9000 rpm limit, i'll use ecu+ to limit me at 8000 or 8500 rpm. What kind of tuning compensations should i be looking at and by how much, or a formula to think about for a start on the fuel maps. and things of the sort. I,m also thinking about stepping up the injetor size to 1050 or 1150cc, so just to check would i just need to scale on the ecu+ from 450 to 650 if i went to 1050's from my current 850's that my stock ecu is set to? or just re-chip the stock ecu? and keep the scale at 450 to 450. I will supply any other info any of you need or curiosities you have. Thanxs in advance.
Oh and my idle is set at 1000 rpm if that changes any thing... Big cams...

I don't really have any pointers. On the injector rescaling, try to make the ratios the same between ECU+ settings and injector sizes. That is:

current injector/stock ECU setting should equal ECU+ injector scale ratio

So I CAN scale it over to the 1050cc injectors being that I have my ecu set for 850cc injectors as is. I ran the car with the 850's scaled 450/450 ran fine.
I geuss the qeustion is how will the ecu + react the the extra .3 liters? And hw might I tune for this kind of change?
