No, thats to convert a auto to manual...I want to convert a MANUAL to AUTO. I'm doing a project for a friend and he has an auto, im trying to use an old ecu I have laying around...

If you would have looked in there you would have seen this link, http://www.pgmfi.org/twiki/bin...anual

Which tells you exactally what you were looking for.

thanks, no...i didnt see that link. i just read the post. but...any idea how to do it...i read the stuff... i dont understand adding 4.7kohm-5% at RP18

whats that jargan

Re: Convert ECU (murmur9)
 

oh yea...my ecu's off of a 97 DX i believe


i got it off someone on ebay when i did my y7 swap

If you look at the ECU board you will see a spot marked RP18, in that spot you need to add a 4.7K-5% resistor. Just find an electronics store someplace around you and tell that that you need a resistor with those specs and they will know what you need. Then when you get it just solder it into RP18.


When you go get resistors you should make sure that they are the same size (physical dimensions) as the ones in there now and it will make the soldering a whole lot easier.

ok thanks a lot, one more quick question...i seen it posted before...if i just solder it...it will still work...it wont take away from resistance or whatever? can i use a typical soldering iron that my dad has, or do i have to get one with a extremely small tip? should i avoid using too much solder or whatever its called? i did a swap...i should be able to do this right?

The only way that you will want to do it is solder it. Any soldering iron will work, but I would go for a small tip as you have a small dot to hit. You shouldn't need to add any solder more then what is already there, and if you do just a small amount so that it doesn't hit anything else that it is around.

Thanks, I got the ECU open, i found the rp 18 and 17...but i can not find the IC 16 5050 ...i see ic22,ic17,ic18,ic19,and ic 20....wtf
