GT2871R elim and meth timing plot

**Molotov** · 10-19-2010 02:26 PM

I was bored, about 52 degrees outside and 23psi

**EBG 18T** · 10-19-2010 03:31 PM

looks good. Is that a 3rd gear run?

**613B6** · 10-19-2010 04:50 PM

Do you think their are any benefits to meth at that temp? I've been running 15 degrees at the same temps around 25psi with no corrections, I'd push it further but my rods might jump ship..

**Molotov** · 10-19-2010 05:10 PM

yeah 3rd gear pull, cylinder 4 was pulling 3.8 average on back to back runs, everything else was 0. Don't know if meth is really making a difference right now but I'm on T9 and a ridiculous amount of timing added through lemmi.

Does adding timing on lemmi links advance the overall timing curve? And wouldn't the software still pull the timing if it detects any type of knock...(I'm talking about not meth installed setup.) Sorry for the off topic.

**613B6** · 10-19-2010 05:19 PM

Correction will pull timing no matter what you throw at it, at least in maestro, not sure where limmi adds it.

Molotov, you got rods?

**Molotov** · 10-19-2010 05:28 PM

No rods, just waiting for it to explode. Planning on doing a 2.0 build this winter and boy would a blown motor be a good motivator/excuse hahah.

I am surpized you are pulling 3.8 on cylinder 4 and everything else being 0.

Even at this temp the meth does make a difference. At 60F my IAT's have actually been below zero at some points.

**Molotov** · 10-19-2010 06:26 PM

Yeah I was surprised as well... I took out a couple degrees from my 80 degree temp tune months ago. Logged again with the same settings today and apparently it's still right on the edge. Go figure.

How much meth are you spraying? I am shocked you can get that much timing using a small Race Tec intercooler, even with it being pretty cool out. I never tried adding in timing when it was cold out on top of timing 9 when I had Revo and a gtrs with meth, only did it when temps were at like 70*+ and it would just pull timing if I tried to lemmi more in. That was with a Eurocode intercooler which is similar in size to the Race Tec.

cyl 4 is the furthest from the Tbody.... so meth doesnt get sprayed as much to that cyl. thats why he is pulling timing in cyl 4.

**vinny.dtw** · 10-19-2010 06:52 PM

So basically you don't really need to lemmi any timing up until T9?

**Molotov** · 10-19-2010 07:02 PM

I'm spraying 375 cc starting at 5psi and full spray at 15 if my memory serves me right. And I can't imagine needing to use lemmi if you aren't at T9 unless you want to add .25 degrees at a time on top of a lower REVO setting. My posts may have inaccurate information at this time, as I have been drinking.

Thankyou. I figured there had to be a reason. I have been seeing about the same timing retard accross all 4 cylinders, but maybe that is cause i have the meth nozzle tapped into the intake manifold.

.75 at a time

ahah ya that is the way to do it... after finding out how cheap it is, I might tap mine their also

Tapped where on the manifold? Nozzles for each runner?
