Default Revised MOTIV 750 Dyno Results - 06-02-2015, 01:14 PM

Hey guys,

Was finally able to get our 135i strapped down to test the latest tuning changes.

Since last go around:

1) Changed WG spring from 10# to 15# which allowed us to hold more boost to redline than before. With smaller turbos like this I'd say the control range is more like 2.5x WG spring rather than the 3-4x we've previously been able to hit with larger turbos.
2) Corrected some issues with bank to bank variance on the fueling as well as issues with negative fuel trims.
3) Reverted back to the basic Cobb VANOS maps. Previously was running some changes suggested by MOTIV but for whatever reason the basic Cobb stuff seems to run better than what Jake suggested as well as anything I came up with during testing.
4) Reduced false knock and retuned for MBT which wound up being a bit higher than where timing was set last go around. The false timing drops were causing us to under time it a bit.

Current issues:

1) The lvl10 would on occasion slip during runs.
2) Above 30psi several runs had misfire faults, in random cylinders. The car has NGK 5992s @ .018 currently. It's time to start experimenting with alternative plugs for those of us running > 30psi.
3) Still get some timing drops from time to time. Especially in 5. Need to sort out if they are false.

Overall still very pleased with the MOTIV kit. It's doing exactly what I wanted it to do. If I can get this 700whp down the 1/4 mile without misfires or trans problems this is an easy 140mph car.

Nice job. Interested in seeing that level 10 tranny if it can hold that 700 hp without having any issues.

Nope. At least not whatever LVL10 is currently selling people.

I think with time people is going to see that level 10 is more like level 0.

The lvl10 is better than stock and at least on our very light weight 135i it works "OK". But it's far from bulletproof at least in what I have. I'd say it's good for around 550lb/ft. But what we need is one that is setup for 700lb/ft.

I feel like that's not that substantial an upgrade over a "stock" HP21

Are you considering a 6MT swap? Or just calling it a day at these types of power levels and hoping for the best? Can certainly understand if you are out of patience with this.

The stock one burnt out around 500wtq on mine. On the 135i I don't race it that often, so I'm just going to ignore the problem for awhile. Next race is in early Sept. After that I'll decide what to do with it. Don't really want an MT. We already have that with our E92 FFTEC setup. But don't want to continually swap the trans around testing things either. It's going to need an engine one of these days so hopefully by then there is some proven auto trans solution out. Whether it's lvl10 or someone else.

Congrats, great numbers and nice graph! Looks like it was still climbing, any reason for sitting it down before it flatened out?

It stopped because the autos have a lower rev limit (for now).

Since MT is slower, there would be more to do in the manual front for a tuner now that new tables will be revealed. More MT cars would be beneficial for the development. Or is it a longer process for Jyamona to do the ground work and no chance yet to make 6MT quicker than AT?

No idea, you'd have to ask Jake @ MOTIV on the hardware specs.

Looking to get one this spring. Your dyno looks much better than what is on motivs site. Would this be about the limit for the stock engine? And the motiv900 only for built motors?
