How does this log look??

Can anyone see if this looks normal?

Car slow as, and not pulling after 4.5k just goes a bit flat.

Running big16g on evo0 engine.

All of the figures in that log look waay out of wack to me!

What are you using to log ?

Try logging the following items only.
RPM, Knock, TPS, O2r, IDC's and mabye Timing.
This will give us a good base to give a quick answer

I agree, the numbers are all out of whack. Getting over a thousand percent on your TPS is pretty impressive. :?

This is an mmcd on a palm505 then converted to an excel spreadsheet with mmcd tool.

have edited the post above, i screwed up the table :?

Thanks guys

Not sure if the INJD were coming up at idle it was around 0.7% and at 6k on the spread sheet INJD were 78.9%

Usually a 'safe' limit for your injectors is 80% so you're pushing the limits as it is.

Having said that, it looks like you're running pig rich. The o2 voltage is coming up as 1V+ usually the happy medium is between .7 and .8 (so I've been told) though I've seen a bit over .8 on my car. The ECU is also trying to lean the car out a shitload at idle. The FT02 is reading at 30%, which means it's trying to trim off 70% of the preset/standard fuel amount for idle.

I'm presuming the AIRT (intake temp) is in farenheit, but even so that's pretty damn hot. About 50 degC.

Despite being rich as all hell, you're still getting a little knock on the way up. While it's not dangerous amounts, it still seems odd.

Are you running a SAFC? How is your intake set up? Have you still got the honeycomb in the AFM? What chip/computer/injectors?

Edit: just noticed that your coolant temp is at 26. Celcius or farenheight, that's bloody low. Was the car warm when you took it for a thrashing?

A few numbers there still dont make any scence.

The car was definatelly warmed up first.

I have swapped the AFM and hooked up a new BOV (think old one was leaking) the car is running alot better now. Still rich but it comes on boost harder.

Not sure whats going on with the air temp (it cold here) I dont have any cold air set up?

Piping is pretty much stock.

Time for a new chip i think!

Have you done this since the last log? Best to put up another one for comparison sake. Best way to see what's going on in a good pull is to go from ~2k rpm in 3rd and pull all the way out to whatever you'd usually rev to at WOT.

Check your coolant temp on the guage and on mmcd once the car is or should be warmed up. This SHOULD be about 80C and about half on the guage.

What computer/injectors are you running? I see you say you have an evo0 engine.. if you are running the yellow top (510cc) injectors with the stock AFM on a standard VR4 ECU it'll be rich and not running great, due to the standard VR4's being tuned for blue top (450cc) injectors.

50C is pretty high air temps, even for the stock intake. unless you've been sitting there idling for quite a long time.

Yea yellow tops, stock afm sounds like its the issue then.

Have a 055 afm to go on so might get a chip burnt to allow for that at the same time.

Heres the latest log, with a different(stock) AFM and the new BOV.

For some reason the mmcd tool changes the air temp and coolant temp to a different format. i just compared the exel file to the pda log and they are different.coolant is aroun 96C and air temp aroun 40C. Baro changes aswell its around 0.99 bar

Cant seem to get INJD to come up with mmcd tool but it max out @ around 75% @ 5500rpm

Yeah, if it's a stock computer and not an EVO-0 or RS ECU, then having the yellow tops in there will just be making it run poorly and really rich. I have been told that if you put yellow tops as well as an 055 or 609 AFM in to a stock VR4 at the same time, they balance each other out and the car runs as it should. You could always either break one of the std AFM's you have and use the connector to make a patch cable for the 055 or just splice into the old wires to connect the 055 instead of cutting them so you can swap between the two and test it out.

The rest of it seems as though it should be OK then. When I finally get my photo's back I should be putting up an install guide for fitting the 055 into a stock VR4 so it's nice and neat and factory looking.

Sweet, Dre said the chip was for 510s but as its running so rich i might just try put on the 055 and log it again to make sure its not leaning out.

Let me know when you get you pics back , be great to see what youve done.

Cheers
