Thanks codgi! I learned a lot from your tune. I'm using 91 Octane at 21psi. I used your tune as a guideline. It feels better and the map looks a lot smoother.

 

EvoScanDataLog_2010.09.06_18.33.05.zipHere you go. I'm learning a lot. This is after I adjusted my timing. Much better!

At 3800 RPM and at 266 Load I'm at 4* on the log but 2* on my timing map. In reality I'm at the 240 Load and the timing is 4* at 240 even though my log says 266. Let me know if I have this right.

 

timing on the log looks ok but i would suggest smoothing the rest of the areas other than just the load your car is hitting in that one gear. There are no AFRs or boost in the log but judging by the load and airflow if you have no cams it looks like you are at ~24psi? tapering to ~20. No knock is good of course. Post up some boost and AFRs if possible.

Any details environmental conditions and was this on a level road?

 

Hey looks pretty good at 5* peak and afterwards. During 3656-4500 there is some minor timing fluctuation and load drop (could be due to the late pull) but i'm sure the car feels much different.

It would be good to rescale your load to at least 280 or 300 and do some further smoothing. Make sure you align the fuel map too if you rescale.

It would be good to put the gas down at 2500 and get a broader pull while in third. 3500 RPM is a little late.

Maybe a more experienced tuner could chime in.

 

Agreed... start pulls from 2500 and watch for tip in knock. You should hit full boost by 3500 so smooth the timing map like i said earlier

 

Thanks for the advice. When I log shifting and normal driving I notice 1 or 2 knocks but no big deal.

My LC-1 stopped working (ordered new sensor) so I'll be able to log AFR's later and I just ordered an Omni Power 4 bar map sensor from Buschur to log boost.

I'm at high altitude here in Colorado and the weather is in the low 80's, no humidity (so dry), on a level road. I notice some knock (1-2 knocks) going uphill. That's my favorite time to pass and leave people in the dust .

 

Thank you for the advice!!! I just rescaled following Ludikraut's https://www.evolutionm.net/forums/ec...-viii-ecu.html

I can't believe how exciting this is This is addicting! Too bad school didn't make it this fun to learn.

 

I suppose my timing maps is probably never going to be "fully tuned", but here is one from today.

If it's not there, you can add it.

The MUT request id is 0x33 and the scaling is x-20. The unit is degrees, obviously. The value will be whatever is in the current cell in the timing table. You can use it to verify that it is looking up the value you think it is.

Excellent, cheers!

 

I don't know how useful that will be seeing as the ecu interpolates between neighboring cell values so much. Half the time the logged map value won't match. Granted, it will be in the ballpark.

 

and if you turn of in the periphery bit the "enable high octane igntion map lookup" than the car will run from the low octane map and can not pull the timing on knock ?

 

does the periphery bit work like that confirmed?

if so, you could sort of use it like an altmap. Could be a useful tuning tool.

 

That is what I'm curious about

 

Hello,

what do you think my timing map ? Fuel : 100octane shell v power, Evo 8 forged 2.0 internal stock cr, 9 turbo, 3"tbe, 26psi 3250-6000rpm than tapper to 24psi 7000rpm. In load 3250-5500 280 load, 5500-6000 270load than tapper to 240 until 7000rpm.
I coudn't hear any knock by det can..
