G1 plus to G4 upgrade


Recommended Posts

I have a ca18det s13 silvia running a very old link g1 plus ecu. Wire in unit with hand controller. 

I would like to upgrade it to a more modern ecu. Not sure which type but it a street car

So want to keep it as simple as possible. Atom?

The g1 plus has a decent tune for the current setup.  Can I get the tune out of my g1 and transfer it onto the new ecu?

Can this be done pre install say by link if my ecu was sent down or is it fairly simple ie DIY possible?

Will the install be a complete rewire or is there a conversion plug or something?

If the loom is in good condition you can cut the plugs off and crimp on the new G4+ plugs(s).  For a basic 4 cyl turbo I would typically go for the Monsoon, you may find the Atom just a little restictive in terms of number of inputs and outputs. 

As for the tune it is not really convertible, but you could manually copy over some aspects such as ignition table as a closer starting point.
