Here are my maps and a current pull of gears 1-4. Tell me what you guys think. I am still running my MBC until I can get a handle on my timing and fuel. Then I will switch over to the gm solonoid/mbc contraption that I saw malibu jack running and a 3bar MAP sensor. The timing map was created from a skeleton in UCC.

Looks nice to me. Are your AFR's what you were tuning for, or do you have more tweaking to do?

Sorry... Not much free time anymore, but I'll take a closer look at it tomorrow..

I would add more fuel in you 80 column if that doesn't fix it lower the boost from 6250 to 6500 the stock ECU is trying to pull timing.

Personally I run my car a little richer but to each thier own

Also please buy a MAP sensor and hook it up. It is vital when looking at logs IMO

yeah, i'd add a touch from 5500 to 6250.

After comparing your map to mine, in the normal load sites you're actually running a touch more timing in most spots than i am, but my intake just goes nuts with the maf settings

CT9A I am mainly looking at AFR's right now and next I will dial in the timing.

bbbwrx Ok will try adding more fuel. But question: If my AFR's are already in the 11.4-11.5 isn't that rich enough? Is the fact that the ECU is pulling timing a good enough indicator that it needs more fuel?

WarmPepsi Will add some more fuel in the ranges you suggested. I see that I am a touch lean in that area. The normal load areas are just a big freakin mystery to me. I noticed that driving down the highway my ECU advances timing to 40 degrees. I don't think I am going to be punching 40 into my low load sites...sheesh. I think I may leave the ECU to control low load since it seems to know what its doing.

MalibuJack No worries man.

The fact that the ECU is not happy means that the ECU is seeing the first staged of knock. On my car I would lower the boost but most people don't like that option. So you can add fuel and if that will not work then lower boost.

looking at that first map,

you have to have some serious transition from the ecu to the utec map.... ur values in the low load sites for timing are quite low (in my opinion hee he)

Can you elaborate on what and where you mean?

Well to fully see the transistion and to tell if there are problems you are going to need to make some logs that go from ECU to UTEC control. Then check the ECU timing vs the UTEC timing. On my maps i give them about 2-3 degrees before I think they are way out of wack.

But since you made your map from a skeleton of the UCC logs I bet your transistions are pretty close.

But now looking at your timing map it does look a little wierd. But I am not sure what RPM is what without labels.

I think your hinting at what I think your hinting.. hehe..

You can make smooth transitions in your timing map from CLF to OLF, or you can use more timing to build more torque, but remember that builds more cylinder pressure and you have to take that into account.

I know my low side is messed up. But here is the thing, when punching it, I get very little data from the low end of the rpm/ load spectrum because I blow through that range so fast in 1st gear. How can I get more data? Its not sampling fast enough.

I noticed that while cruising around on the highway I looked over at my dashboard and my timing was advanced 40 degrees by the ecu...Is anyone running that much advance in lets say 3000-4000rpm and 0-10 load? Seems awfully high.
