Gobbles Posted September 20, 2017 Report Share Posted September 20, 2017 G'day from Oz I have had this ECU (I assume it is a G1) running my 1UZ-FE in the boat happily for many years and has been very reliable. I have recently bolted a blower on top and obviously need to do some tweaking, i have got a tune that is running the same set up on a similar boat that I can dial in but the ten dollar question is are these too old to be PC programmable or do i have to dial in manually on the hand controller?I know the general advise would be to upgrade to a current ECU, which would be nice but am trying to avoid the cost and work of starting from scratch.

Simon Posted September 20, 2017 Report Share Posted September 20, 2017 That unit is pre PC tuning so is going to be a hand control job. Quote Link to comment Share on other sites More sharing options...
Gobbles Posted October 27, 2017 Author Report Share Posted October 27, 2017 I have come across another option of replacing with a G3 unit, would this plug straight into the existing loom as it has been confirmed that model is PC programmable. From the pics i have seen it looks like the same sort of case and plug. Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 27, 2017 Report Share Posted October 27, 2017 Perhaps they look similar but the G3 is very different. The G1 had a 17 pin connector whereas the G3 has 26. The G3 is actually a much better ECU and can even be upgraded with the G4 firmware, but you wont be able to load or copy a G1 map into it or anything like that. It will be no easier to upgrade to the G3 than it would be to upgrade to the newest G4+. Unfortunately, there is no direct, easy upgrade path for the G1. Having said that if the only change has been adding a blower it should only need some tweaks to the main fuel and ignition tables in your original tune, if you find a tuner that still remembers how the G1 works there it shouldnt be a massive job to do that.

Gobbles Posted October 27, 2017 Author Report Share Posted October 27, 2017 Thanks for the feedback. I should have guessed it seemed too easy The biggest issue is finding someone prepared to part with a hand controller, just like hens teeth. What about a possum ecu? Have seen one of those on trade me Quote Link to comment Share on other sites More sharing options...
Simon Posted October 30, 2017 Report Share Posted October 30, 2017 The PossumLinks are dedicated Subaru units and are not able to be used on alternative applications. Quote Link to comment Share on other sites More sharing options...
Gobbles Posted October 31, 2017 Author Report Share Posted October 31, 2017 Thanks for your help Simon, looks like i have got my hands on a controller so the next step should be easy. Quote Link to comment Share on other sites More sharing options...
