Default Rich as hell but no power

Took her around the block on my base tune rich as hell and little to no power. Ran with no airfilter as that is still on the way. anyone interested i have a log here. I am gonna shoot for more like 12.5-1 as i got more power below 4600 with leaner afr but unfortunately my MS locked up on me before i could save the finall tune. This is with WI comming on at 4 psi no air filter No MBC, 460 cc RX7 injectors, and my new WB 02 controller. at least my diff isn't making any trouble.

i am not running spark control via MS so that reading is just what the tables say i believe yep around 90 or so today. The AIT is siting beside my clutch master BTW And i am running with no hood on. No it is an inovative the tune from AL is just that frigin rich. it hits 15 or so some times i new controller and sensor. i think it is reading right alot better than the other one wich stuck at 15-1 or 11-1

is your log showing a max of 14.0:1 AFR? it should be hitting 20.0:1 when you coast...

Can timing control affect your AFRs? I was under the impression that is can and will, so if you aren't running ALs spark tables either then that could also affect your AFRs.
That's sort of a WAG on my part as well.

I am on stock ecu for timming base set at 10 btdc. no retard and no knock. I still believe this is mostly a fuel issue you FMIC guys run way to rich.

did you say you have WI on? too much water will kill power in doublequick time by dampening the flamefront.

Try reducing the amount of water you're injecting.

In order for the VE table to be correct, you need to have appropriate values entered in the engine constants menu (REQ FUEL, INJECTOR OPENING TIME, etc)

and here's the hard part: the wb may read false values with your WI.

Just downloaded and looked at your log, 11 AFR isn't *that* rich, I aim for 11.8:1 afr's. You're not going to see a massive gain from tuning to an afr of 12:1

Rich as hell is the guage pegger over 10:1. I think you're looking in the wrong area for picking up lots of power. you get the best power gains from timing.

Personally I'd tune your car up and run it for a bit till you're happy with the reliability, then hook up timing and re-tune, you'll gain a lot more power from being able to tune/control the timing.

I am now thinking that my Lc1 is not reading true at all. To expunge any rumors it gets much better when the water hits, and smoother. I just took it for a spin with 2scoopsofhooah running my laptop and we smoothed out the low boost out a ton but my power is still not there. This is the same amount of water i was spraying on stock ecu with 7-8 psi so nothing has changed there. The only variable is my fueling. Everything else is exactly the same as it was with stock ecu making 200 whp.

This is wierd, why are you running 13:1 air/fuel ratio under cruise? Running that rich is not going to help with power at all.
