what is the best chip to modify the p28 ecu to run a b18b/c engine? or should i just get the ecu that pertains to it?

 

I offer ECU chipping services as well as chipped ECUs at very reasonable and competitive prices.

b18b is requires a non-vtec ecu such as P75 or PR4 it can be chipped but unless you have cams its pointless to rev the non-vtec to more then 7k rpm

b18c (GSR or R) will work very well with P72 as far as maps but low vtec and rev limit means that you will not be getting the full potentail.

for GSR with dual runner (stock) intake manifold stay with OBDI P72 (USDM specs is by far better then JDM) there are few program avalible but only recommended if you required for larger cams or built built motors.

P28 is an excellent platform for the single butterfly DOHC VTEC motors it offer varitey of programs and its cheap.
for the street JUN, J'S and Superchips are excellent. for racing Mugen/Skunk2/PYR and others which run rich and have few sensors disabled.
