I have a .bin that I was told is set for 370cc injectors and CA18DET MAF, but I'd like to make sure because I'm going to need to change it to 450cc and ZMAF and I need to know whether or not to set up the .ini accordingly.

Does anyone know the exact addresses in the HEX code I can look at to determine what this chip is tuned for MAF and injector wise? I tried searching but couldnt find exactly what I need.

thanks,

-Matt

Your K value should generally be set at B7h if it's for 370cc and stock MAF

Do you know the hex address for the K value?

Thanks man! I'll tell ya what, if you collect or trade aftermarket tuner CA .bins I'll send it to you in an email and maybe you can give me your opinion on it (it's an unaltered .bin I pulled directly from my aftermarket JDM ecu's EPROM).

thanks again,

-Matt

p.s. If you're interested please PM me your email address.

Sorry, how do you determine the new K value for larger injectors ? Do have a ratio like that :

370cc = B7 hex= value in dec
so (444*value in dec)/370= K new

and the result in dec translated into hex gives you the new set up for the K value ? Wink

mbmbmb23, replied Wink

randall, the other way round: B7h=183dec, new K = (370*183)/440 = 154 = 9Ah.
