Are all your sensors reading correctly in the ecu (through datalogging)? VSS is a common one, but could be a few others.

Errrmm I'm not sure. I have no way of data logging. When the engine was in the aerodeck vtec worked fine. I would get a fault code for speed sensor wouldn't I. I'm sure I dissabled the speed check in crome.

Thanks for all the help mate!

Iv tried my other p28 which has a different map on it and still no vtec. But this one brought up code 36, traction control. Iv searched and someone said to dissable injector test circuit. So I will try that tomorrow. But would this cause the vtec not too work?

Did you get anywhere? I'm after a map for a friend for a UK B18C4 also!

Sorry to hijack, a friend of mine has asked if I can burn him a chip for his brothers engine conversion, he has an OBD1 B18C4 Engine, and is using a Conversion loom also so it sounds like the same kind of setup perhaps? He has IAB's at the moment. I cannot find a b18c4 base map anywhere!? Will a p72 coded rom work on a p28 ecu once socketed so that the IABS can be enabled for now?

if the hardware has been added to the ecu for iab.

My understanding is that B18C4, B18C2 and B18C1 are all the same. C2 is Aus/NZ spec, and C1 is USA spec - AKA 'GSR'.

P72 ROM should do the job for any of the above.
