Default 04 WRX fixed most of my Knock problems with UTEC. Just 2 problems now!

yay for me. I just dropped time -1 across the board (10-100) from 4700to5300 rpm.

Now I only got 2 problems

1) I still get knock when the control switches from ECU to UTEC. basically once in 1st, and once everytime I shift.

2) I get max boost at 4300rpms in 4th. ***!!! I know this has something to do with running too rich at the low RPMs. Leaner = higher EGTs = faster spool. So can I just do -10 across the board from 0rpms to 2750 rpms from 10-100?

much thanks for all the help!!!!

Maybe pull some timing in the 5200-5500 range?? Looks like the transition from factory to UTEC timing really quick like that 13 knock count in first is too big. Id say try pulling 2 degrees at and taper to the surrounding areas. But, I am far from a tuner so dont expect it to be perfect. That is just a ROUGH GUESS.

Does anyone agree with me?

Kitbar,

Take the lowest timing values from 5000-9000rpms and copy them to the 0% column starting at 5000rpm. Do the same for the fuel map; copy the highest fuel values from the 5000-9000rpm boxes to the 0% column.

Hope that helps...

Cheers!

Hey guys thanks for the suggestions, I'm gonna try it. Basically match the timing values for ECu and UTEC to prevent a big jump in timing. awesome.

Also I was wrong about boost not coming till 4.5k rpm. I did some test runs in 3rd and 4th this morning. It was a bit warmer. I got full boost at 3.1k rpm! Yay!

But I got a huge huge smell of gasoline whenever I floored it at that RPM in 3rd and 4th. Is that normal?

Gasoline smell? Hmmm, I know the base maps are pig rich but I've never encountered any gasoline smell when going WOT...

Your IDCs are pegged at 100%. You might want to reduce the amount of fuel. Although I don't recommend doing so without a wideband O2 sensor to measure your true AFR. When I reduced my AFR to 11.5, my IDCs maxed at 89%. This varies from car to car so take it with a grain of salt.

Taking your car to a tuner is money well spent. Most will be able to wring out more HP than you ever imagined possible.

Cheers!

Yes, I am thinking of going to a tuner about 4 hrs away on the thanksgiving week. I am concerned because if I get it tuned, will the turboxs permanant fix for the 04 rex cause my tuned maps to be worthless? I think the permanant fix should make the 04 rex go rich immediately when you go WOT rather than waiting a few seconds. Is that right?

No, the tune will not make your tuned map worthless because your tuner will come up with a new map. You can even ask him to make you 2 maps... ex. one performance and one economy.

Yes, the permanent fix is supposed to do that but seems like it's going to be a while before it comes out.

Cheers!

Kit,

FYI, I've been getting knock like crazy the last two weeks, when I was never getting it before. I've narrowed it down to 'winterized gas' from the BP/Amoco station I fill up at.
