Timing Curve

Awesome Steve! Good work man. Whenever my microtech comes in (5 months and counting 
) I will be picking your brain for info. The main thing to get sorted is the timing. Fuel maps are easier to work with. So keep doing what your doing and keep us updated!!!

Uh... holy shizzit! I'll have to see how close I can get to that I guess. I'm basically going to tune 7 psi boost and 12 psi boost, and max out the timing until the JandS lights up. Then I know I'm tapped out... so we'll see! I have the JandS adjusted to the point where I'll get a random trigger or two every now and then but in general doesn't flinch. So that is dialed in. Now with the microtech I can go through and find the timing! I'm running rich like I said before (11.8-12.2 ish) so yeah... but I'll be curious, and once I do get it tuned to where I want I'll dyno and post the curves and we can all learn from it hopefully! I'm just hoping I come up with something good
.(I half hope to beat Terry's previous dyno on this car without going to 13 psi
)As you can see the timing is a little on the advanced side. I was starting to get VERY occasional lights out of the JandS. I actually turned the sensitivity up even more on it from where I had "calibrated" it to just because I wanted to be cautious. I didn't hear or feel anything unusual out of the engine. But I can definitely tell you that where it use to be gutless after 5K it certain doesn't have that issue now. It pulls VERY hard through all rpm's. I am having major boost creep issues with the Profec B spec II that I have... so I was had to keep things at 8 psi or I hit boost cut too easily.
Just makes me awfully nervous with how advanced all that timing is. It is easy for me to pull it back by making a simple adjustment to my air or water modifiers and it will pull all RPM's and boost levels back on timing. But that is where I was just running at and made several 0-60 runs (best was like 7.4, which didn't seem right) So any thoughts or cautions would be appreciated. I trust the JandS yet at the same time this timing just seems to be SOOOO advanced it is ridiculous (compare it to Shawn's map up higher in the thread).
WOW!!!! That is a big difference from shawn's. If the J&S says you're cool, then so be it. Keep the timing in so you will make more power. So have you found out how close to stock these values are???TurfBurn said:Well I tuned the car for the most part. I started getting chicken toward the end and stopped pushing things further.
BTW: AFR's are about 13.9-14.7 up to 5 inHG and then 2 psi -10psi is about 11.3-12.2
Here's why:
no idea how they compare to stock... I'd really like to know as that would be HUGE in making feel better. I trust the JandS but at the same time, it's like SO far advanced compare to what you would think... so I don't know. i worry like that the JandS isn't hearing it or something.. last thing I want is to take out my engine block! But whatever I guess!
Well...I wouldnt bother a lot with the timing.
What I think is that you may not need so much timing retard for up to 10psi if your fuel curve is rich.
I had 11 degrees retard when I blew my engine (went lean), enough retard good for up to 15-17psi.
The 30psi protege is running 20 degree advanced on his haltech.
Just be sure to have enough fuel.

Well i pulled some of the timing back (I'll post my final map) because I got some detection on the JandS (it was pretty sensitive though.. would indicate when I hit bumps for crying out loud).
But the bad news is... my motor blew like none other. I'll get pictures tomorrow night hopefully. But I have large pieces of metal all over, and no oil left in the engine (because it is all over the track). (no it wasn't detonation, oil starvation, or running lean... the ONLY sign of trouble was some random misfires and running really really rich and then the straightaway became an oil slick and a cloud of white smoke)
I'll post a new thread to discuss it... lets try to keep this one pretty on topic as it can be a very useful thread! no need for it to go OT on us and ruin a good timing thread.

There you go! Made just for you.

.Yeah, could be that you injected too much fuel on one cylinder, a plug failure, and the cylinder could have drowned in gasoline and thus, blowing the motor.
Could be a head gasket problem
Or a "long run" boosted problem, probably some slight detonation that your car may have experienced before the microtech....
We will see.

I noticed that 3 and 4 ran hotter than 1 and 2 during plug inspections. 3 and 4 were a bit white, but didn't show any signs of metal vaporization, or any of the other things I've seen in pictures that are supposed to indicate detonation. I attributed it to the fact that the car runs around 14-16 afr in the low low throttle ranges when on the highway and the fact that my fuel pump that i just replaced would cause the car to occasionally lean out to near 17 at idle... but yeah... hopefully the tear down will solve the mystery.
Ahhhhhh fond memories....... Well not really but all I can say is there is no sicker feeling then hearing your motor let go like that.igdrasil said:
Steve, I don't think that your motor let go due to tuning. That car was the first 3rd gen protege to be boosted and went threw a lot when Terry had it. I just think it was on its last legs. I should be getting my microtech in any time soon and will be using the same timing that you have for now but will have to see about higher boost.
