Thanks again Bryan, car feels great!

 

Who?

 

SO IT BEGINS

 

Enough said. Should have called that first log something else.

 

If you guys like spreading of information for everyones good please don't do things to get this thread locked/deleted.

 

Just take a wild guess and leave it at that.

 

I did and it wasn't a wild guess either

 

Nice job. How much timing did you pull from the mid range? I wish we could share these maps

 

1 to 2 degrees around peak trq. The biggest thing that helped was giving the ECU a progression of timing advancement instead of a flat line. I noticed the ECU gets really grumpy when it sees flat timing.

This also made the car feel meatier because the timing was well... advancing.

 

+1 - What timing did you retard, and to change it from "flat" you had to add some at lower loads too, right?

Were there any mods added since the previous tune? Was the original tune a custom or mail-in?

Thanks

 

Not if the timing was too high to begin with. I dropped it down and had it progress smoothly up. Smoothed and progressed everything from lower rpm to high rpm and from lower load to higher load and vice versa.

I answered this earlier in the thread:

Same mods. Except for the weather mod. It has been quite hot lately in California, unfortunatly people still have to drive places in any weather.

 

Could you post a timing map, modified enough so that no pro-tuners get their knickers in a twist, that illustrates the "progression of timing advancement"? I have been trying to figure out what that should look like and am definitely reinventing the wheel in the process.

 

I'd be very interested to see this as well. Mine is a little more "flat" that I'd like for it to be. On the dyno my car was down on tq but I've made a lot of changes since then. I don't have any knock issues but I'd like my maps to "progress" a little more.

You guys are more than welcome to dl MY map.. it still needs work and is too aggressive for pump gas (currently working on an alky tune) http://justchil.net/dl/evo/tuning/ALKY_15.hex

Actually I had forgotten how nice the "stock" rom is for this.. as far as "stepping" your timing tables and such...

 

Sure thing:



This is not the map that was used for the car in this thread.

 

So the timing was "off the sweet spot" by about 1-2 degrees around peak torque on a generic mail-in flash for a car on 91-octane California fuel? That seems pretty reasonable.

Glad to see you were able to find some gains with fine-tuning and smooth out the power delivery.
