ECU Compatibility

[lexington]

I have ECMLink V3 in my galant VR4

My Automatic Eclipse GSX 1993 does not have an Eprom ECU.

Can I put my VR4 ECU with the V3 chip into my GSX?

If I can, won't the mounting points be different?

Note, this GSX is an AUTO trans.

Thank you

You will want a manual cars 450s and fpr, if you swap to a speed ecu.Trust me.Its a stock upgrade

I haven't added any extra air so why would I need extra fuel? I still have aircan and stock exhaust.

I know that 1g's and VR4's have different base fuel pressure but can't I just change that value in ECMLink?


I am only trying to diagnose my idle surge at the moment and get some logs to make sure everything is in order.

Because if your going to swap the ecu, you mise well add more fuel too,and now be able to brake boost.

Its just easier to do it that way for an auto, more fuel add a few more psi to that 13g,and have at it.Your fuel pressure will be off swapping to a manual ecu anyway, so add the fpr and the 450s while your messin with it?

Your idle surged could be a few things have you tried Search Results - DSMtuners

You can swap the ecu, you'll just have to compensate for the 43.5 psi fpr, and 390cc injectors in link.
