LS/Vtec timing questions
Well i just about have my CRX project done and i need to make a bin for it in Crome.Im new to the Bseries so i have some basic question.What timing maps do i use for it?The stock P30 203 B16[adjust effiency for 1834cc] or import the 273 B18C timing maps into it?Also it is a fresh built motor i need to break in and i was wondering if anybody else was using 750cc injectors and if you were having to play around to get a decent idle in Crome?Im thinking i should just run the stock injectors to break it in so i have a good air fuel at idle and basic cruising etc till I get the rings seated.The setup is as follows:
81.25mm B18 block
B16 head with GSR cams
B18 9.4-1 SRP's
CDM "super T70"
MSD 749cc injectors

Use a GSR. bin with ABT+ 2.0 and FVFT 1.99.
Do basic injector recurve; 240/750 (only it will NOT be 750 as MSD rates at 85% duty... do the math) and then keep upping the offset under the advanced tab until she idles sweet and clean like stock with a stoich AFR. From there it's an easy cleanup on NA range and light duty tuning boost.
