just wanted to do a couple dyno pulls (JR TUNE INSIDE)

figured i’d do a couple dyno pulls to make sure the car was still running like it should, the day it came off the dyno… and to my surprise, she’s running just as good with ZERO knock across the board

no tweaks nothing, just 24-25psi 93 octane, the way it was tuned by JR himself…

god damn thats alot of torque

pffffttttt a lowly ltwon on a small shot was on ya , even wit e-85 in your tank lolol

good numbers man i like it

When was the car tuned?

Sick! I gotta get a ride!

This was back@ The Shop?

This was VDR at dynojet setting.

When was it tuned, PETE?

If it was tuned in the summer months, then I’d hope that it would be running the same as it did when it left the dyno. :lol

Dyno it when it’s 20*f outside. I bet you’ll need to make some changes to the tune then. :slight_smile:

my car was tuned when it was 38* out and raining…

and I wonder why it runs like ass when its 90* out!

Probably just runs like ass because it’s down on power, since it’s 90 out

no I mean the difference in idol and shit. The car doesnt drive/accelerate any different according to my butt dyno.

on a fuel injected car it dont matter if its dyno,s in the middle of winter or 90 deg … the comp will make the changes needed unless the tune if fucked . thats why all cars that are injected have a air intake temp sensor

Tuned June 3rd or 5th

It really depends on the car then, I guess. Normal driving might (and should) be fine if the o2 sensors are ok, but the P.E. fueling curve isn’t affected by temperature changes. Doing WOT blasts down the highway in the middle of winter on a summer tune is a race against time (and a melted piston or two).

The reason I say that is because (for example) a car that’s commanding an 11.7:1 AFR at WOT may be OK in the summertime and not experience any knock or lean symptoms, but in the winter the cylinder airmass is a lot more dense. You really need to add fuel to the wot tables in order to be safe in the cold weather.

Running lean up top when it’s cold is never a good thing, lol.

I think John meant MAF cars/tuning aren’t effected by weather.

The MAF doesn’t know how dense the air is. The cyl airmass is estimated by the ecu using math calculations. So if it sees the same amount of air being sucked in and uses the parameters that you told it to in the summer time, it then sprays the same amount of fuel and the car will obviously be lean. This is why MAF-only tunes can be dangerous, especially if you run the same one year round.

Of course, whether or not a narrowband o2 will pick up on that is anybody’s guess, however I can guarantee you that they will not under heavy loads and WOT because the computer uses a preset afr at those times and ignores the input from the o2.

Maybe Pete’s car/ecu operates a bit differently. Does the evo have a wideband from the factory?

Its prob rich as shit. lol

Granted I don’t know much on the matter, but I’m referring to a MAF that bases it’s voltage on how much a heated wire/film cools as intake air passes over it. That means it knows exactly what the air density is, because air density is a function of temperature and humidity, no?
