I have a 93 hatch, I just put in the d15b motor with the p08 ecu. I have the CEL code of 19 which is the automatic transmission lock up valve. which teklls me that the ecu came out of an automatic and I have a manual. How do I fix te CEL light...I read it somewhere once and I don't remember how to do it. Thanks.

no need to chip the ecu... just requires moving/removing one or two resistors on the board. see pgmfi.org

Here is a post I made a whalie back when I conv. P28 Auto to Man. I dont know if P06 would be exactly the same but I hope this helps you out. Check PGMFI.org too. Ill tell you right now its really easy to do if you got the right tools and you know how to use them.

Maybe this will help. Scroll to the bottom of the above link.

How to convert an automatic ECU to 5 speed specs

First, let's find out if we have an automatic, or a 5 speed ECU. If you don't want to plug it in and throw code 19 (automatic trans lockup solenoid) to find out it is an automatic ECU, then look at the code on the side. If the second to last number is a 5, then you have an automatic ECU (for OBD-1 USDM ECUs). If the 2nd to last # is anything but a five you have an ECU for a 5 speed. If you have a jdm obd-1 ecu, look at the last 3 digits: 900 or 901 will be an automatic. If you were unfortunate enough to get an automatic ECU, then read on and learn how to cure all your problems.

For Jdm Pr3/Pw0 ECUs:
Move the jumper from R68 to R67 (both locations are to the left of the ROM)

For USDM OBD1 ECUs p28
Underneath the ROM there is a row of resistors labelled with RP__ . Remove RP17 and install a jumper across RP18.

For JDM OBD1 ECUs:
RP18 (in the same location as usdm) needs to be lowered in value from 2.4k to 1.4k ohms.
