Your paranoid about running rich?

Then you shouldnt be touching a rotary.

Whoops, I meant lean***

Well youd have to run it lean on boost to blow it up.


running it in vaccum areas and idle you cant blow it up running lean.

But you can run too lean with too much timing and do things like melt turbine wheels, flatten springs, etc.

I`ve been playing with the Microtech`s for quite sometime now. What I`ve notice is that Rotaries run excessively rich or desperately lean, so the AFR`s ratios have to be on the money.

My AFR'S settings are: 6 X 850cc injectors and Dual Supra Twin Turbo fuel pumps / static pressure set at 40 psi

12.2-12.8 at idle
14.7:1 at 25"hg and climbing to ->13:1
13:1 at 0psi
12.5:1 at 1 - 8 psi
12:1-11.5-2:1 at 8 -20 psi
10.5-10.8 20 psi and more

Running water injection / race fuel my load point timing is 7-9 Degree B TDC and increased in the RPM curve.

Remember I`m running a Auto FD 13B Mild Street Port.

13b small bridge port 2 x 550 injectors and its happy at 11.4-11.8 at 2000 for idle

An engine with a small bridgeport should be idling around 1200-1400 RPM and whatever ratio makes it happy. Mine likes high 13s. 2000 RPM in the 11s is kind of a poor tune.

Bridgeports love timing. Run at least 18 degrees at a lower idle and try less fuel. 15 degrees split...

mattmarrx3

havnt even touched the timing yet its only just to run it in a bit will finish it off in a few weeks when altanator is fixed

What is involved with raising the idle while running a standalone?

Cant wait to get my laptop dongle. My AGRs are retarted rich. I've fouled a set of plug in a month already. Previous owner screwed around with the idle and gps so hopefully it's just that. I don't like seeing AGRs of 10 while dailying in vacuum. I get better gas milage in boost lol.

If you have a BAC valve, adjust the AuxRPMSet value on screen 29.

If you don't have the BAC, then use the hard idle stop screw on the throttle body and then recalibrate the TPS.

Thanks Aaron just to make sure, when adjusting the hard idle stop screw, you don't have to change anything on the maps right?

I was about to make a thread to find an answer to this. Thanks aaron!

when you change the idle from the throttlebody you need to recalibrate the tps.
