i have a jdm b18c with a 99 SI ecu. it runs fine and everything but was just wondering if a GSR ecu would be better as far as VTEC x-over and just in general. i heard it's not good to have an ecu that was made for a 1.6L to run a 1.8L motor not not sure if it's true. thanks for the help and any info.

 

anybody?

 

A gsr ecu would be ideal. The fuel maps, ignition timing, vtec engagement point is different on a b16 then it would be on a gsr.

The ideal solution would be a chipped obd1 vtec ecu with an obd2 to obd1 jumper harness

 

thanks so much. i will look into the chipped obd1 vtec ecu with an obd2 to obd1 jumper harness. what is the advantage of doing it this way. i will be searching like a mad man.

More tuning options for OBD1

 

which JDM B18C do you have? the GSR version or the ITR version?

the GSR version

 

then for sure the P72 would be much better.
Unless you've changed the intake manifold.
