that's too much knock...i wouldn't feel comfortable with that tunning...

 

Old Bubba wuz smarter then u think. He owned a garage up at the top of that ther hill and after you felt that first kick in the overalls from turning the distributer clockwise 2 whole turns, he would be waiting fwith a brand new 350 he had in the back for 20 years with 100s more

 

He advanced the timing 720*? ITS NOT POSSIBLE...or is it?

 

 

+1 thats crazy mad knocks.

 

That timing map is way too agressive. I have a IX so this may not translate directly but it gives you an idea. I dont think your car is going to hit the targets on your timing map - at least not with that fuel and boost.

As I suspected your timing is WAY WAY too aggressive. "Bubba tooning" at work I am sick and tired of these so called tooners and their damned addiction to timing advance. The idea that "a lot of advance makes more power" is bullocks. Sometimes LESS is more.

 

that poor engine... i would be pissed if i paid for that tune.

 

Bollocks, engines need as much timing as they need for Mean Brake Torque. Generally at a given boost level its only possibly with high enough octane. Sometimes its better to run less boost and more timing than less timing and more boost. That is where a debate can start, though I do agree with you in everyway Naj.

Someone did rescale the map so they kinda have an idea of whats going on.

 

I disagree. It is MTBT. Minimum Timing for Best Torque. Anything more than that is pointless. The best power from gasoline happens @ 12.5:1. The closer you are to that number the more power the car will make. Ofcourse this is theoretical and there are other factors that prevents the EVO from getting to 12.5:1. I have created a map that pulled timing and leaned out the AFR and it put down 312 hp on DLL with olny a TBE (hi flow cat). It is a 93 octane map and timing is around 16.5 peak and boost is 22 psi.

The Evo 8 is badly tuned to begin with. Running 21-22* of timing and 9.8 AFR in the top end is not my idea of a good tune. A good tune is what GM did with the GXP with 12* maximum timing and 12.5:1 AFR. Of course the car has direct injection, but the MS3 also has direct injection and is tuned like crap.

 

The people who are saying that the timing in that map is too aggressive need to stop talking, you don't know what you're talking about.


His timing curve looks like a flashed ecu, a pretty normal one at that....Original poster, send me the full map and I'll try to find a problem, but right now I'm thinking you fux0red up your car.


I think a healthy evo will see 10 degrees of timing at peak boost rising to 20 degrees, plus or minus a few on pump gas. If you think 7 degrees of timing is a lot....oh lordy I'd hate for you to see my logs with 0 knock hah.

 

if you think that's aggressive look at mine =p

 

Naj you misunderstood what I was saying as there was sposed to be a period in there somewhere. Its spelled Bollocks not bullocks, my mistake for pointing that out. I get my terms (MTBT) confused sometimes but you knew the one I meant, thank you.

I agree that the tune is crap.

4TUN8, you are new here please show some respect. You can run as much timing as you want on whatever setup you want. There are lots of ways to do it. You can run meth, you can drown it in fuel, maybe your pumpgas is 94. I can buy 100 octane from a pump that I drive to so I spose that qualifies as pump gas as well. That timing map is aggressively advanced. Maybe its been awhile since you have seen a stock timing map for an VIII or IX. Thats about 13* more advance than stock. That is alot of timing.

I have run up to 9* of timing at 23psi on 92 octane with no or little knock. I then started experimenting with more boost on pump gas and have been successfully running 25psi at peak torque with 4 or 5* advance.

Running a bigger turbo and running cams changes all the parameters for what you can get away with. The timing that you run is tame compared to DSM's that have a 20G (I will go on a limb and assume you have cams for the power you have listed). At least on the west coast you cant run more than 4 or 5* (which is what his logs show timing being dropped to BECAUSE of knock) on 92/93. I respect that you might have ran alot of timing, but for whatever reason his car is not letting him. Fuel is obviously an issue, but the timing is still trying to get to 4 or 5* regardless.

 

You can run timing that high if your car is tuned @ 10:1 in the high end like yours is. In the videos your car is spewing soot from the exhaust because it is so rich.

Your car is also heavily modified with an after market turbo and god knows what else.

Here is a pic that I took from the video. Your car run @ 10:1 which is not much different than stock.

 

"knock knock..." "who's there?"...seriously, throw in a Walbro...and get that tune cleaned up.
Did he say who tuned him?
