quick question for you experts. I am having hard shifting knock problems from 1st to 2nd only. I was reading on here about smooth the transition timing from your high RPM point to the next gear RPM load. So for instance from 7,000 in first gear to 5000 RPM in second gear the transitions have to be relatively smooth to prevent knock. My question to you guys is the rule of thumb of no more than 3-4* difference between those load cells even when shifting to the next gear still hold true? Or any advice for those that run quartermile would be nice. Thanks.
FYI I am hitting about 280 load about 5000, and 240 load(soon to be 250) at 7k on the stock evo 7 turbo.

But for the timing part:
No shift knock here, about 1* change by 10 load.
No reason to be less smooth than that on upshifts:
A lazy shift would look like (depend on gear):
245 load at 7000,
140 load at 5200
265 load at 5300.

It's a nice map. Is it 93?
With that taper aren't you able to run more up top?
And watch it I see a 11-12-11 in your run. This area need work it also has some 12-13-12, 12-11-12.
Give a shot to this smoothing tool. It should clear all that wrong cells: https://www.evolutionm.net/forums/ec...t-version.html

yep, it's 93
when logging it registers 15-16's up top where I have 12's and 1* at peak load area, where I have 3's
so can't rely 100% on the map

That drag shift knock could be induced by worn engine mount, exhaust hitting something...
But for the timing part:
No shift knock here, about 1* change by 10 load.

your timing map looks beautiful btw. much smoother than mine at this point.

hmm looks like 4* difference on your "lazy" shift. Looks like I am now in the ballpark. Did a few logs and things are definitely getting better. It's amazing how much timing you are running on 91. Your timing map looks very very similar to mine on 93-94. Surprised you have't tried to put any numbers down on the VD? My current VD numbers are 400 WHP, 395 foot-pounds of torque. We are putting down the same load at 7k..except I am running 280-290 peak load at 5k falling to 240 at 7k.

My timing isn't "that high" for 91 octane. Many owners run this timing. My first maps I ran 8-9* at 7000rpm and I still had knock everyday. With the work I've put in the map smoothing it and working timing.... now I can run 10-11*. This include working the fuel map and boost as well.
At this point, adding 1* anywhere in the WOT part of the map starts to randomly knock.
I can assure you that my knock light comes on about once a week. The car is knock free. One thing I had to do to make the car happy was holding 5* at higher RPM than before. After 5500, the car is more timing hungry (VE / boost are dropping).
I think it's a little inflated: 400 out of your VII 10.5 turbo... (which i think is VIII equivalent)
