Microtech Idle afr
#30
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.

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...

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.
