RPMs bouncing from 700-1k I'm every time I start up my car

So I just got e85 tuned last week im completely stock besides 2 step colder spark-plugs gapped .02. I got tuned by Cary the car runs fine except the idle when I turn the car on I posed a video about it on Reddit.

Just tell Cary. I had similar on my first rev with Paul's map and he cleaned it up in the next revision.

It happens to me every time on E85. I just turn off cold start and my car idles fine now.

Never bothered to fix it cus cold start is loud and I don't want to annoy neighbors.

Okay glad to hear that fixed it, I told Cary on Friday he said he will do some changes on his end probably will get the revision tomorrow or Tuesday.

Yes, cat heat off for E85.
Why heat the cats if E burns clean anyway?
Just extra noise in the morning…

I also have the Cary Jordan E85 map. I left cold start on initially and had the same exact rpm issue, about 10-15 seconds after a cold start. Turned off cold start and it went away.

That's weird. I've had cat heating off because I've had aftermarket downpipes for a long time but I thought all that does is keep the idle at a slightly higher RPM for a pre-determined set of time. I think that because no matter what the environment I was in, cold/hot/whatever it would always take the same time for the idle to drop before I set any of my tunes to aftermarket DPs, etc.

What are all your bolt on mods? What did you clean your MAF sensors with?

Hey ! It's fixed now it was tune related cary sent me a revision and it no longer does it. Also I have 0 bolt ons just 2 steps colder sparkplugs and Cary's full e85 tune. The car pulls like a train I put like 10 cars on stock hellcats and I beat a 10 speed FBO e40 Zl1. God I love this car haha

Yeah that tune puts down about 630whp from what I've seen. A lot of folks I know run it. This engine is ridiculous. Definitely get at crank hub fix.

Yep they did mine in under a day. They got a way to do it quick and dirty. Just keep an eye on AF:Rs, I don't think Cary would do this but I see a lot of tuners running folks lean just to squeeze power which is very dangerous long term.
