Okay, now that I have more time to compose, I think the dyno proves that methanol (I ran 50/50 boost juice) makes a big difference even if sprayed before a twin screw not after. I went in at 493 rwhp-468 rwtq and today after adding meth and tuning for it left at 610 rwhp and 592 tq… wow...
Oh did I mention it took all the spark I gave it, was spinning tires like crazy and I couldn't stop grinning..... still need to tweak the MAF curve some with histogram, but it's getting closer...
Ok so I was messing around with tune, tweaked the torque and inverse, upped spark, put max retard at -8
Spark. Took car for ride and tried to obey all the speed limits etc. I can’t post log so I took some screen shots. This is with methanol running. Basically I took shot of log in closed...
well after watching that video above, maybe the too rich condition is causing false knock. The hp kept climbing as I upped the spark.... we'll see when I run the meth and add spark what happens. I'll post back.
Thanks, I’ll watch that for sure. I guess if I made double the horsepower at the crank from stock that isn’t too bad. I just thought she’d have a little more.
That is what I had the timing limited to… I was slowly adding it back but ran out of time and I wanted to see if the meth made a difference. I’m gonna make another appt to play with it more.
I didn’t realize that about the barometric pressure . Good info thanks.
I tried to upload the Hp tuner log said it’s the wrong extension to upload here. Lito doesn’t use hp tuner, (at least not with me) he uses SCT which is more alien to me lol. My wideband doesn’t plug into my SCT so I had sent Lito videos of it. The digital gauge is hard to see on video. I...
So in this dyno run, I see I need to tweak the MAF some, I'm commanding .85 Lambda and I get between 11.5 and high 10's especially around 3.6 volts upward. Every time the AFR dips into the 10's the engine shows some knock. I have it set to allow it to add 1 (to be safe) and is pulling up to 2...
If I drive with a light foot I don’t get into any boost. I have the methanol set to come on at 3psi and max at 10. So if it would go out with a methanol tune I would just drive normally (is that possible lol)
Cats are on but gutted. I did notice that the mufflers aren’t flowmaster they are flowtech… maybe they don’t flow good enough? Headers and x pipe are Kooks
After a WOT run when the fuel cuts out (DFCO) it stutters coming back on. I mentioned it to Lito. Maybe that is because of the 25 he has it set at??
He also has DFCO set to instant so the AFR goes super lean even between shifts. Pops on slow down I don’t like it gonna change it back...
The tune the car came with has way more aggressive spark tables. the tune in the SCT that came came with says 93octane and methanol. When I bought car it was eating plugs and the kid who owned it was frustrated. The BAP wasn’t working easy fix. That and 2 step colder NGK PLUGS.
Speed shop...
I was going to run the 50/50 boost juice from snow but couldn’t get the damn thing to come on . I got it working now… I’ll have to dyno again. The methanol should allow me to increase spark and further lean out my AFR as the methanol will make it richer I believe. So maybe I’d be around 600 rwhp??
