Eprom ecu

[tiburshok]

Hi need your inputs, it happens i found a eprom ecu md169547 which came from jspec vr4. My current ecu was md128618. Will the md169547 work as replacement?do i need to swap wires? My plan in future is to install ecm link and tune my car. Is it ok too that the ecu was AT? And my car was manual? Thanks

plug it and run it.

This subject has been coverd, recently too. It will damage your abs pump. Other pins are not the same as well.

There doesn't look to be a knock board on the top ecu.

No the ECU in your car uses 450CC injectors, where the auto ECU uses 390CC injectors.

I think i dont have abs pump.my engine is transplant and the chasis were ordinary cb lancer.

 

[tiburshok]

Based on i found these ecu uses same 450cc. My plan is to buy ecmlink (lite or full ver) and start tuning

 

[89Patches]

Didn't realize you're in the Philippines. I never thought overseas models that were auto came with 450cc injectors with 13G turbos.

If it were me i'd use the ECU you picked up, if that chart you posted is correct.

 

[tiburshok]

Will socketing it to fit the ecmlink chip will be ok? Also does it matter if its AT or manual?

 

[tektic]

After ecm link no. Your starting with a blank slate.

It looks like there are no knock sensor provisions on that ecu though.

 

[tiburshok]

Any workaround for the knock sensor?

Both boards seem to have the IC102 board in them. If so you need to do some repopulation of the boards resistors, diodes, and jumpers.

upper ECU is from a JD RVR, same ECU pin out as Evo123.

lower ECU is what is being referred to by the OP. knock board on lower left of ECU board...

just have it re-socketed and re-chipped by some of the guys from over there...
