Fueltech Running issues

[Merkle68]

So to start off i’m running ft450, setup with a kiggly 12-1 crank trigger with a 1g green top cas with the larger hole covered. I have it currently are running it as semi-sequential for the fuel injectors and have my ignition setup as wasted spark and cop setup with 4 wire smart toyota coils. I’ve started the car and it stumbles: under acceleration, and low rpm. Any help would be greatly appreciated!

Have you contacted fuel tech for support I would do that it seems easier. Unless someone here uses fuel tech maybe

If you're still on the basic tune, the fueling is probably very rich. Save a log and attach it.

See if this does it.

It should be an .ftml file.

I had to save it as a csv, it would not let me upload the other way for some reason. I could try to send it another way if it would make it easier.

might have to do that. Again, have you tuned the car yet? If not, that's why it's falling on it's face.

No, not yet I'm pretty much a newbie at this stuff, I bought my fueltech ecu about a month ago and just yesterday got the wring and everything ready to fire up. I did notice that with my foot on the throttle at 1000 rpms (give or take), my afrs jumped around between 11.5-10.

You have a lot of work to do still then, the base map is just that, just to get it running and usually is VERY rich, it's drowning the engine with fuel and probably maxing out he o2 corrections.

Thanks for giving me place to start, I removed a lot of fuel on the overall tune to get it to start and Idle. I haven’t had a chance to mess with it since monday. I currently idling around 11.7-12.

I personally do not use fueltech on a dsm. That said jason does and it sounds like from what you have said the car is VERY rich.
Do you have experience tuning or someone who can help you?
The base tune's are just that base. My experience enough for most cars to start and idle and that is about it. The rest you need to do.
