haven't pulled code yet, when the 94-95 accord tcu was in it the light blinked then, code came back to mainshaft speed sensor. manual cluster sounds like a easy fix for me

Ok the code sit the same code thrown when we previously had the 94-95 accord tcu in. Code 13 for the mainshaft speed sensor, its not the sensor, because the oem accord tcu had no lights on, but shifted the transmission WOT at 6k, where the integra one holds the gear until 7k. I have compared the circuit diagrams for both the accord, the 94 accord and the integra tcu's.

No luck finding the differences for the main and countershaft sensors. They are the same wire colors and pinout locations on both layouts. Car runs fine just as it did with the 94 tcu, so im done digging. Again the tcu code is a P78 from the 94-95 Integra LS.

The integra tcu does have a location for a PA sensor reading(D3), while the P39 does not have a output pin in the ecu for this.

This needs to include the OBD2 F22B information.

I would imagine you could swap everything OBD1 over from the F22A. Injectors, sensors, distributor guts. I even used the PT6 ECU on an F22B, car ran great.

Same concept as any other swap in this chassis.

Use your OEM engine harness and purchase a distributor for either the JDM 4th gen Prelude TD-60U or USDM 4th gen Prelude (with DOHC engine) TD-59U ECU and call it a day. Disregard the crankshaft sensors on the oil pump. They're handled by the distributor in the OBD1 application. The distributor you buy will be determined by your current car. If you have an internal coil '90-'91, you'll need the JDM TD-60U distributor. If you have a '92-'93 with an external coil, you'll want the USDM TD-59U distributor.

Yeah ended up swapping the dizzy guts. my OBD2 motor came with an EGR blockoff plate, so my ECU is throwing a code 12. Evidently, the ECU is looking for the EGR, which I wasn't expecting, because my motor didn't come with one.

I'm probably going to try to swap the EGR from the old IM to the new tomorrow and see how that goes.

Is the chassis wired for IABs? Obviously, my A1 harness isn't, so I'm going to have to find an A6 harness and swap that in when I get around to it.
