Interesting stuff, that's a lot of work you've put into developing that prototype. I see that the early Denso ECU is your weapon of choice to mod and remap, is EGR removal something you've dealt with before? I assume you would need to enrich the mixture at overrun to compensate for the lean conditio...

Thanks Rhinoman....

On how later models does the mapping do this? I have a 33920-71E70 N1 ECU, can it be remapped?

Rhinoman wrote:Evap. canister can be removed but removing the EGR is likely to cause the ECU to revert to a fail-safe mode.

Is this because the ECU is expecting to see some resistance at that pin? If so would it be possible to replace the EGR with a resistor to emulate it?

Had a study of the FSM and answered my own question :screwy: 34.1 - 39.8 psi. It seems that the SPI and MPI use the same in tank pump. Most MPI systems still only fire one injector at a time and many EFI system require a fair amount of pressure to keep the valve inside the injector closed. Now... wi...

Cheers Twiss, I have read somewhere in the depths of the internet that the pump should be somewhere between 34-38 psi? Though the first thing I noticed about the net and SPI info is that its here, there and everywhere, lol.

It's time to swap the tired G13 for a G16 and I'm going down the SPI route, got no worries with regards to making a new loom etc. as it wouldn't be the first EFI swap I've done, would be the first Suzuki EFI swap though so your collective knowledge will be much help. The lump and ECU etc. are from a...

Superb! Thank you Rhinoman.

I'm gathering info for a G16A SPI swap, looking for the pinout diagram for a 33920-71E70 ECU?

I don't have the complete loom and intend to make a new loom to suit this swap, any help greatly appreciated.

This is my cunning plan! (This makes it five posts so my PM should be good now, lol).

Ah, PM me if you can! I'll need one more post after this to get that PM feature working... I have a cunning plan.
