Update on my MPI Tuner!
- Thread starter acidbug
- Start date
I'm at 0 Fuel Calibration as well. I hit 10 PSI, but it starts to lean out, and kinda fluctuates, so I let off the gas, and press it again, and repeat the cycle. When I 1st hit it, it is rich...even at 10 PSI, it is at 12 A/F ratio, and then it rises, sometimes going to 14's until I step on it again!
Same type of thing happened to me tonight. I now have the NSN MBC and got it up to 10psi and I noticed afte r a few seconds I started creeping into the 13 range. Once I get a damn WORKING laptop I'll be able to take away some timing and add some more fuel!
Any new maps Chaz?

Yeah..i have new maps..but i am having some problems..w/ my wastegate....to be exact..it's the vaccum hose from waste gate to turbo..****** think cut..by fan..and i am boosting above 12psi.. (wow)smp3000 said:
But since the vaccum hose ****** up...my turbo now spools even faster..it's weird(scratch)
Chas
Yeah dude when my wastegate's diaphram went out I could boost well over 15psi or more! It was basically like not having a wastegate at all. And yeah it spooled faster but the speed wasn't there because basically since the wastegate wasn't working or keeping vacuum (since hte diaphram broke) it was liek having a big air leak.
Replace that hose!!!
Could you upload your new maps?

Finally updated the maps and it feels pretty darn good!!!! Chas- how much psi are you running? I'm at between 9-9.5 so I'm trying to figure out if I could add some timing back- it feels a little sluggish up top.
Also, I noticed you had NO timing advance or retard inthe first two columns ont he 8X16. Do you think it would be a bad idea to advance some timing in the first tocolumns up to about 2500rpm?

Advancing Timing under 2500 is worthless. Below that rpm car doesnt need to be advanced. I have tried that before and I can hear the engine knock...if that sound is not knock, then is the valves.
The sound is like what you hear in old cars when they are trying to pull the car with so much effort and nothing. Like a valve clap, knock or ping.
You better add timming up top and pull a lot between 3,000 - 4,500 rpms. Then start to advance but watching for knock.

Right now i am runnin about 12psi..like an idiot..i really havne't had time to fix the vaccum line..But i am not at constant 12..i alwazy let off. just as it hit's 12..so i am only in boost for like 1 sec..lol.smp3000 said:
But on a good note..i finally installed the new PCV Valve..hopefully it will do its trick better than the stocker..it cost me $25.
The reason why it's sluggish is b/c of the amount of timing i pulled out. The car was detonating every now & again...Mostly when it was warm/hot out!
Also added extra fuel to keep my numbers in the constant 12-13's according to the mpi tuner software..
About the advancing timing issue..I am not sure if you want to be adding any timing. Unless you have a J&S.
Chas
I basially used your maps you posted on July 28th and modded them slightly. You advanced timing (1's and 2's) in columns 3-8 up until about 2,500K and then started pulling timing starting at -3 and then all the way up top at like a -8. hehe and you don't have a J&S do you?
Igdrasil- you think it'd be smart to advance timing in the 3-4rpm range? That's right when boost hits hard for me (and most people) I'm positive there'd be knock.

You must do max retard between 3,000 - 5,000rpms on boost, but have it advanced when not on boost.
Only advance it when not on boost and less retard on higher rpms. Basically thats where knock mostly occurr.
Chas - You are risking your engine running 13:1 on 12psi. I blew mine running 13:1 on the greddy with good retard (-12) @ 11psi. Yeah, I did 4 runs, one after another WOT from 1st gear thru 4th high.
right... ok we're onthe same page then.. Ya I'm pretty sketchy on going any higher than 12.8's @ my 9.5psi... so I'll be adding some fuel in the morning and probably keeping the timing maps where they're at.
Today it was 115 or so here and I'm running 91 octane with no octane booster- and not a hint of knock. Seems, I'm adding enough fuel, pulling enough timing, keeping te engine cool enough, and not abusing the car too hard.

I say nix the advance at low RPM's. I tired that but did not see much difference. It actually made my car start a little harder and stumble a bit here and there. Like igdrasil said, pull that s*** in the midrange, but keep some more out up top. Don't add any up there with the MP3. It's always safer and cheaper to pull timing and make a little less power, then it is to make more and blow the thing up.
Pat: Yeah the IC did help a lot. Since the install I havne't had many problems with hearing ping. It's a good IC, nice and thick!!!
Chas: Yeah 91 is as good as we can get out here. Fortuantely I've been using a bit of torco durring each fillup, but haven't for the past week becuase I wanted to see if what I've done will work with pump gas. The Torco, thopugh, makes a HUGE difference. A half can to a full tank probably puts me around 96-97 octane. A full can puts me around 100-101 octane.
Tim: As of this morning the advanced timing down low seems to work ok. I'm not feeling as much lag as I was before and seem to be spooling a bit faster. I'll post my maps today or tomorrow and then you guys can analyze my timing map cause I'm a little confused.
