Ok well I have a 91 crx si and had the pm6 tuned with turboedit so it is already chipped, when i got my swap it was a B18B with a OBD0 mani and cable tranny it was a swap out of a 90 civic and i got a pr4 OBD0 ecu with it...Planning on boosting the motor right awy so here is my question probably really simple to answer but thanks in advance...

Can i just get a basemap chip to run the b18 for my pm6? or would it be better to just get the pr4 chipped? Would it be a b18b or b18a basemap <--I think i rember reading the ecu tune is a little different but not sure if the B18b has to be OBD1

Anyways I had xenocron chip my ecu and will be going to him for this basemap and then a good tune, thanks...Matt

 

just get Chris do do a basemap for your ls motor for the pm6 thats it. PR4/p75 is a much more agressive fuel map than a stock pm6 map

 

Cool, all i needed to know, i believe it would work but just wanted to be sure, thanks...Matt
