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. The following information was all obtained from Hondata.com and the picture was graciously borrowed from them as well.

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 labeled 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.

So! can I just convert my automatic ECU to a 5spd and then plug in back into my car and start driving my newly swapped 5spd car??

93delsolsi · 08-20-2006, 03:55 PM

yes you can

Accordian · 08-20-2006, 04:55 PM

SERIOUSLY?! uhhh ok, so what about the wirring though? to my 5spd? the VSS and the reverse wirring? and what about the shifter needing to be in park? or neutral so the car can start? and the intrusctions you posted don't tell me anything (esp. my ecu), how can I covert my 94 accord ex automatic ecu to a 5spd? it's the POA

its all there... as where it was copied from above, but not for the accord ecu i'm afraid.

the easy way is to just score a 5-spd one from a junkyard/ebay/etc. but it can be done.

perhaps someone on Welcome to PGMFI can help?
