im assuming its obd2a?

i have that ecu running a jdm b16 and it works great, no codes on a 96 db8. however, plugging an obd2 p2p, i get 2 codes, crank angle, and 2ndry o2. it also makes the car jerk due to the rpm's dropping quicker.

the p73 i have now is a loaner, and the shop wants 300 for it, which i think is too much.

which ecu could i get that would not flash codes or jerk the car?

 

It's the JDM B18C ECU
it had the 96-98 style plug ins

Looks like an ITR ECU (P73).
The reason you're throwing at least one of those codes is because your car (probably) doesn't have a chankshaft (angle) fluctuation sensor.

i actually pm'd him a few days ago, but didnt get a response.
does the jdm ecu not have wiring for the crankangle or secondary o2?

thanks guys.

JDM ITRs have only 1 O2 sensor in the header collector and i think (but not 100% sure) that they also dont have crank angle sensor. The ECU you pictured above is a 98spec ECU. 96spec ECU's are # 37820-P73-003

 

im assuming that you're correct about them only having 1 o2, and not having the crank angle because i get no codes and run perfect.

last question, any diffrence between 96 and 98 spec ecu's? is the redline at 8900?

thanks again for the quick replies.

 

As far as i can find out there is no real difference in either but 98specs will be mapped for the 4-1 manifold and the extra 3degrees duration on the intake cam, but a 96spec will run fine in a 98spec and vice versa. VTEC on both is at 5800rpm and rev limit at 8900rpm.

 

thanks alot mugenracer
