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... |
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 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?

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

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