Neither. Pick Precision Turbo 680cc to get the right Battery Offset.

That isn't the "right" battery offset. If you want it to be correct, and the PTE 780 isn't listed in the wizard then you should send one of the injectors to AEM and have it measured.

There is a list of offsets posted on the AEM Forum somewhere with a bunch of injectors that aren't in the wizard yet. I'd bet the PTE 780 is listed there somewhere.

Make sure you get power to the AEM itself. I've had problems before with radio shack relays.

Relays for supplying power to what?

lethal_vr4 · 08-15-2005, 08:14 AM

I have separate power feeding (with switched/fused relays) to my widebands and the AEM EMS itself.

Hmmm, mine works perfectly well connected straight to the harness. Wideband is fed off the O2 heater power on the EMS. Has always worked perfectly fine.

I'm not saying that hooking it up staight to the harness is a bad thing. I moved mine to dedicated lines as I was concerned about current draw. I threw the relay suggestion out there as I have had problems in the past with el'cheapo Radio shack relays failing causing no power to the AEM and hence no starts.

Battery offset just models the characteristics of the injector's dead time vs battery voltage. It does not make major fuel correction. You have to use injector sizing correction instead to do that.

If you look at the 680cc PTE and 1000cc PTE injectors you'll notice both have identical curves but one curve will start higher than the other.

True, if you want an exact battery offset then send them to AEM. I was merely pointing out what 1veryfastvr4 could use now. Denso, and RC injector time tables are much more incorrect for use with the PTE 780's.
