You may also want to have a look at the link fryj00 posted which does indeed do a good job of explaining the FF/PWM relationship and why it's important that these two are closely matched.

Try lowering your PID gain to 20 and doing a couple more logs.

Set PID to 20, surging better but still over boosting considerablely, as well as dipping low.....so the car surges but not as bad now. Here is my settings page

Logs will be below.

My half engine light cam on at the end of every pull, but after 30 seconds of slowing down and driving it goes out by itself. I used to have to restart the car to reset that half engine light.

Do good 3rd gear logs from 2K to redline at WOT without downshifting to assist in the learning process and lower FF to 50.

Yes, He stated wants a 3rd gear pull from 2000 rpm to WOT. From your logs your shifting from 1st through 4th.

I though give it everything as far as the road was would give you more info than you could use sorry. If I'm cruising 2-3000 rpm in 3rd gear and floor it I can't keep it from kicking back to second gear........ how would you suggest a get a 3rd gear on pull?

So if I understand you, you want a full 3rd gear pull, which in my step tropic car is impossible ....... I have to be at 4000 rpm or it will kick back to second gear. Here is much of a third gear pull that is possible with my car.

How does every other step car do it on this forum? You cant start at 2500 and floor it just slightly above the kick down button? Or if you cant stop yourself from hitting the kickdown, get the kickdown blocker I guess

I assume your car has a manual mode. Put it in manual so you can start in 3rd gear and keep it there. I would also do a 4th gear pull if possible.

I tried everything I could do to get what you wanted but in my car is impossible. Not matter what gear I am in while in manual mode I can control when it upshifts, but cannot control it from kicking down when you roll into the throttle .......it kicks down no matter. This is the only logging on long I got this morning

Meanwhile, I made a spacer out of small pvc using feeler gages to measure clearance between the pedal and the bracket making the spacer exactly that thickness before the kickdown switch clicked. In M/S mode no matter what gear you are in it will not kick down but still shows 100% throttle...nice tip.

Since it is raining here I did get a few 2000rpm to redline 2nd I gear pulls.......see if they help........I'll do other gears when it dries up

Unfortunately, best I could do....... there is no area within 60 miles from here to over over 130....... ain't happening unless I drive an hour. Anyways I tried to get 4th gear pulls and they all kick to low power codes at........it's 4th gear limit is 4000 rpm .....setting off high boost codes and throwing the half engine light on, seeing no purpose for that I let off........pleeeeeeeeease tell me I've given you enough to go on.....my resourse here in Ohio are quickly covering with snow and only getting worse. This car has to be really for the fort import race. Please tell me you see something

If not equipped with a BEF menu4 must be set to 3. That is a big problem in this log.

It's easy to spot because the throttle is closed, ECU PSI matches actual boost, etc. Seems like an epidemic of these lately. Why are you guys setting menu 4/2 for non back end flash applications? lol

That's not what Terry means.

Go into your steering wheel controls / JB4 menu. Make sure the speedo dial is on 4 and the rev dial is on 3.

I'm assuming you haven't used the steering wheel controls before? If not make sure to watch a YouTube video how to do it correctly.
