Looking for a bit more info on this. More geared toward the legality and emissions and all that huh-bub surrounding this mod. I tuned my GSX via ecuflash and instead of learning another way of doing it figured I'd throw a spare flashable ecu in the 1g make it more modern I know all I need is a jumper cable to wire it up and a 2g knock sensor. ( http://www.dsmtuners.com/forums/tun...3-2g-flashable-ecu-1g-patch-harness.htmlhttp://www.dsmtuners.com/forums/electrical-tech/418334-2g-ecu-1g-wiring.html) Plus it would make tuning easy since it's already running a 2g maf/2g intake manifold etc. How will this affect my testing results for codes and pass? Anything to worry about? I'm pretty mind set on doing it but want to make sure it won't become a headache at the testers. Let me know, would appreciate anything you can input.

But as far as emissins go.. run a dual ecu.. use the 1g ecu to moniter and control the emissions. So it can collect data for the obd1.. and just use the 2g ecu to controll the injectors and timing.
That makes no sense. Think about this. You put a 1G engine in a 2G car, right? The engines are the same, everything's the same. The emissions controls are the same, the solenoids, the EGR everything is the same. The difference is the 2G ECU has more inputs than the 1G, making it far superior. The 2G ECU didn't really have issues with the caps leaking. Yes, there's some wiring involved, but the outputs and triggers are the exact same, just make sure you've got anything reversed that needs to be reversed to make everything match. I passed emissions in 2012 with just a cat, that's it. Most test facilities don't look under the hood for everything. It's too costly for the time it takes. The shop only makes so much out of the emissions testing they want it done as fast as possible. In short, your car does not fall under the new emissions rules, so you don't have to worry about them checking your readiness monitors. All you need is a functioning cat and a tune that doesn't suck to pass emissions with these cars. I passed mine on exactly what I have now. 1450's, Kelford 272 cams, the whole works. The 2G ECU also has an input for the rear O2 sensor, great if you have a wideband and wish to keep running a functioning front O2 sensor.

Rob was telling me about when he did a 2g ecu in his 1g, you might want to talk with him and see what his experience was like.
Haha Ryan nice catch some how I missed that. Jay man you must be drinker some stellar juice to come up with that one!! I can just imagine the mess it would be under that dash.

2g just has two more features that I know of. Second OBD2 port, fan control.

Jay, the ECU has nothing to do with how much power the car can make. The tuning is the same in both ECUs. The 2G ECU is far superior because it can do the following:
2 O2 inputs (Front and Rear) Fan control MDP input
You can have 2 maps on either platform I believe, and they can be triggered when a certain output is triggered (FPS, EGR).

I did this back in the day before they made 1g link. I made an adaptor harness. Lots of solder, lots of shrink tube, and lots of weed and patience. IT WORKED, and worked well. Its been done and like Ryan said, no tuning advantage these days, just the ability to have more sensor inputs.

Well from what I remember... With weed comes lots of patients! Were you a doctor prescribing weed?
