Nearing completion of 2jzgte engine conversion i have found out my Haltech Interceptor piggy backed with factory ecu (auto) is not going to work with the signals and parameters of my new 2j setup. What might be the best way to do the new setup? I am considering a Haltech E11 and Suprastick SS-V4 but not sure how it will tie in with the rest of the electronics on factory ecu (a/c, dash etc.) Also Haltech Interceptor will be for sale when removed. Any advice from the guys who have gone through the conversion would be greatly appreciated. Cheers

Why are you using a piggy back?
a 2JZGTE and auto trans into a Soarer is about as easy as a swap gets, only a few wires to change on the body plugs for gauges, warning lights, and mph/tach signal.
No need for a seperate ecu to run it, just use the stock 2jzgte ecu and plug it in the 2jzgte harness

I would get SSv4 and wire it to stock auto wiring. Then get whatever ecu of choice and make a custom harness for injectors, coils, crank and cam sensors. pretty easy that way.

I have been advised that the crank angle sensor is different on the 2jz engine, and sends a different rpm signal than the 1jz did back to factory ecu to run the accessories (dash, a/c, trans) can anyone confirm or disagree with this????
Have also been told by others that they are the same and should work fine, with the 1jz factory ecu and harness with the new ecu and wired loom for fuel, ignition etc?

Why wouldn't the factory ecu with a piggy back do the job? And how exactly and why would you want to use a 2jz ecu when you need you standard ecu to run everything else?
My 2j has been running for a while now on just a standard 1j ecu, no piggy back and still making 200rwkw on 11psi. Not to mention that the AF ratios are dropping into 9s at some stage, which will soon be fixed by an emanage.

Thanks for your replies all sorted, the points on the crank for crank angle sensor were bent and butched and we weren't getting a constant rpm signal, replaced now and engine running.
Apparently some 1j - 2j supra swaps have completely different crank angle teeth points and need to be swapped, in my case they were the same only damaged.
I am using my 1j ecu and upgrading the piggy back because the interceptor is limited (like can't tune past 20psi which is fine for most 1j setups) compared to a full ecu , so a Haltech E11 will get wired in to replace it and motorplex here i come
