just did an auto to 5speed conversion and the motor cranks but doesnt start i am using my stock mobilizer (auto) and using the 5speed ecu i wasnt sure if that is why it wont start? since i know most people use the boomslang and go obd1 and dont have an issue witth the mobilizer
my friend was telling because my 5speed ecu had mobilizer they dont match but if i go obd1 ecu it will start since the obd1 ecu didnt have a mobilizer make sence? can anyone help me with this i tryd to search it couldnt find anything if this has been askd ebfore sorry and could i get a link maybe?

 

i think you mean IMmobilzer. i think that if it was the immobilzer, you wouldnt even be able to crank it.

 

go obd1, go to your local dealer to have the ecu matched to the key, or some locksmiths can do it for ya. also, is the green key light in your cluster on/flashing when u try to crank??? best bet is obd1 p72 or even p28(with im butterflies tho)

 

i meant without butterflies with p28

 

Take both ECUs to someone who can solder and swap the immobilizer daughter boards between the ECUs.

To convert the auto ECU to manual, move the SMD 0 ohm resistor from location RP13 on the bottom of the PCB to location RP14 on the top of the PCB. The 0 ohm SMD resistor is identified by code 000 etched on it.

Also, what year is your manual ECU? Depending on the year differences, you might want to convert your auto ECU to manual rather than swap the daughter boards.

 

they are both 99 preludes base models
so take it to someone who tunes think they can convert the auto ecu to manual

If they are competent, and do exactly what I posted above, It will work fine. That is what I am running in my girl's '99.
