865hp 363 and QH X3Z

Unread post by Chris93Cobra »

Hello,

Currently running a 363 that makes 865hp with Terminator X. Not too happy with it can't seem to get the LTFT to stay around 0 for more than one day when editing the VE table. I think that the problem is the way that the Terminator X Learn function works. If you are on a cell and correcting it with stft values that move to ltft, it raises or lowers the values depending and then smooths the other cells around it depending on how long you stay at the original cell. I think this is causing me to run in circles. Wide Open is dialed in within 2% always. I do have good experience with a Quarterhorse on my previous setup. I am just wondering if I switch everything back to the EEC-IV will there be any issues with keeping up with the engine. The wiring is in great shape. I had to disassemble the stock harness to build the Terminator into it. I would have no problem assembling it back to original harness.

Below are the specs:

363 CI
7,500 Redline
865hp / 730ftlb
256 / 265 @ 0.050 duration, 624/632 lift 116 LSA
FIC 1200CC Injectors
On3 Fuel Systems - 2,000 Gas / 1,400 E85 rated.
MSD Digital 6AL CDI Box
Holley Dual Sync Distributer

I have the fuel system in place wired into the Inertia switch triggering a relay so the stock ford stuff could still be used.

anything over 7000 rpm youd be better off going to a digital ignition and tossing in an eec-v.

its easy enough to mount a ve crank trigger and vr cam sensor then just toss in an 03/04 luxury sedan ecu
