Alright guys! Well im gonna be chipping my current stock p28 in the next couple days and putting crome on it and i was planning on doing some wideband street tunning with it!

Now i have tuned TONS of d16 turbo's with crome and had absolutly awesome results! Usually keep around a 12.5:1 afr around 10psi and under and maybe 12.1:1-11.9:1 afr over 10psi and always just kept the timming real conservative!! Always with awesome results!!

So my question is? What map do most people use with a b20 setup?? I have a b20b bottom end, gsr head, type r cams, dual valve springs, skunk 2 intake mani!! I was thinking maybe a stock type r map would work good??

Second quetion... what kind of afr's am i looking for with a N/A b20?? Ive never tuned for a n/a setup!! What kind of timming am i looking for!! This is all going to be tuned in crome!!

Or does someone have a bad *** map they already made threw crome i could use as a basemap???? thanks!

 

anyone??

Use the stock ITR timing tables until you get on a dyno.

AFR are correct but with Crome you can't use stock ITR tables (OBD2 they import all wonkey). Just use a P30 base and use the fuel multiplier to increase the fuel.
