Who says you can't make an RX7 idle low?

That's with the A/C on. My idle puller works sometimes . . . . . but at least it still holds good oil pressure when it does this.

i can't stand a high idle. i have every one of my 7's running at factory spec idle and each has a functioning idle compensator (12A) or BACV (13B)

I had my streetport 13B sitting at about 550, but turned it up a bit and haven't bothered dialing it in perfectly.

i don't think anyone ever says that... My SP13B with a aluminum flywheel idles perfectly smooth at 700RPM.

My SP 13B will idle happily at 600 RPM when warm if I really want it to, but I set it to 1000 for easier cold starts without a choke.

I think before I deleted my trailing my car was idling at about 1,100 but thats also due to no choke and starting my car early early early in the morning for school so it would start easier. And sometimes on a hot start it'll pick up at like 300 then slowly climb back up to regular idle.

Just need to search more on how to wire up a new tach signal in conjunction with my MSD...but all the explanations leave me scratching my head.
