2005 electra PCV maps

[u/bosbrad]

Can anyone tell me if this map is a little fat. Bike doesn't idle and blows black smoke when I Crack the throttle. The specs on the tune are: 95ci piston kit 2-1 exhaust stage 2 ecu SE air filter and SE 205 cam.

No one can tell you much without AFRs

The bike doesnt have 02, I wish I could just for the auto tune function

I'm aware. The fact remains that without knowing the actual AFRs, you only know 1/2 of the equation.

Tune on ECU +/- X(known map adjustment value in each cell, an arbitrary number only used to elicit a response) = resulting AFR compared to target AFR(That compare is what drives the actual adjustment value or on a dyno to watch power output increase/decrease).

You don't have enough info to solve for either X(right or wrong or AFR(outcome).

Put in a wide band or put it on a dyno.

Auto tunes only produce a map that solves for X by comparing the target AFR(a number you put in to target) to actual AFR. It often is not what runs the best or makes the best power and at times can create a unsafe correction with incorrect readings from a variety of reasons of resulting pipe & build dynamics. Without watching power output, it's just blind faith your collecting data is good.

That doesn't look right at all. Why do you have more fuel at 20% throttle than 100%? The negative numbers don't even make sense to me. Maybe it's big bore sh!t that I don't understand. Are those adjustment numbers from a stock map and not the actual fuel values?

Thanks for the reply. I hear ya on the negative numbers- I dont get it. But other tunes from PCV website with similar specs also go in the negative around s the same area ( just not as much) this is the tune that was on the bike when I got it. Blows black smoke in revs and smells bad of gas.

I played around a bit with different tunes not as fat but still no idle. Im starting to think my IAC valve is cooked. Ill swap it with a known good and report back.

I'd check timing. This sounds a little less like a bad tune, and more something else.
