    Procede Rev3 Log review

    Hello, this is one of my final logs from over the summer that i had sent to vishnu for review. I just wanted to see what you guys thought of the log and how my car was running. I tried putting it in datazap but the site was not working.

    I'm not familiar with Procede logs but to me it looks like you have a lot of timing corrections. I don't like. Am I reading it wrong?

    those timing corrections were noted as "slight" and i was told that everything was fine to run and to enjoy the car. Click here to enlarge

    I agree about the timing. The column "CAN Actual Ign Advanve" should form a nice smooth graph, but if you plot yours, it looks like saw teeth. The DME is trying to hit a timing target, then is correcting itself to 2 degrees around 4500 rpm, then to 5 degrees at 5700 rpm. Each time it ramps back up but those major changes in timing targets are an indication that your engine is not happy.

    In my limited experience, I would think more octane or less timing is what you need, or maybe cooler plugs (NGK 5992). However, because of my lack of experience, I don't know what reasonable timing would be, so take my advice with a grain of salt.

    What grade of fuel are you using?

    BTW my plugs have under 1k miles on them and the intake ports were cleaned 3k miles ago, all injectors and coil packs are original.

    why are you posting? Your limited experience and lack of knowledge only makes the op more confused.

    Look, I'm not going to get in some multi-thread, text based slug fest with you. I gave the OP good advice about reducing timing, running cooler plugs, or raising the octane of the fuel. He's already using 93 so unless he wants to go with race gas or E85, he should try one of the other things mentioned.

    Same advice as other forum reduce start boost from 60 to 55, up ignition advance from 85 to 90 and re-log. 16 for boost on 93 octane without DP's is pushing it.

    easier to look at here:


    log 1:
    http://datazap.me/u/admin/mr-snail-log1
    log 2:
    http://datazap.me/u/admin/mr-snail-log2


    first one is ok, just the one timing correction. second one has a couple. does it get worse and worse with the next couple pulls you did? there's a wee bit of throttle closure, but nothing toooo crazy.

    These were the last 2 of 4 logs I did. My computer crashed after the first 2 so I had to pull over and re boot to start again.

    Your intake air temperatures are very low during these pulls, starting in the 70's and ending up in the mid 80's, which isn't surprising because of your intercooler and because it's fall (not sure where you're at but it's been getting quite cold here).

    Your AFR's seem a bit high to me, as do your fuel trims. For instance, during the second run, at 4500 RPM, you trims are 31 for each bank, boost is 15.5psi, and AFRs are 13.9 and 13.7 for banks 1 and 2 respectively.

    It's interesting that your AFRs are so high and so are your fuel trims. Are you sure your fuel pumps are meeting their targets?

    It was quite cool the day of the logs mid 50's in ny. I haven't logged fuel pump info and am not familiar with it for my procede.

    Debug Byte 4 is the LPFP voltage. Shivster recommends having a look at the pump if its voltage falls below 2V during a WOT pull. Agree that there does not seem to be a good overhead in the fueling aspect of your pulls. post a screenshot of your user adjustables; probably requires a bump in the OL Fueling scaler.

    Up your Map 1 Open Loop to 90. Post a screen of your Map 1 AFR Table.

    After speaking with vishnu i am told the only thing left to do really is start doing all the maintenance on the car to get the car to perform optimally. They state there was a timing drop in the log but it recovers (im no tuning expert so its hard for me to judge if this is ok or not). They suggest that the wavy afr and fuel trims are due having stock 53k mile injectors, coils, and O2 sensors that could probably use changing. This is disappointing because i had planned to run e85 next summer and i am now unsure if that is a good idea.

    The waviness of the AFR plot could be caused by old sensors (slow response), but that doesn't explain why it is running so lean. You have to consider how low your IATs are too. If you had done this on a 90 degree day, I am willing to bet the timing would look much worse.

    I know people throw injectors and coils at this car, but those are not normal wear items. Coils wont cause a lean condition, and the injector usually fail in such a way that they dump too much fuel into the combustion chamber, which is the opposite of your problem. Your engine is have trouble getting enough fuel in.

    Before dropping money on upgrading all of those parts, you should try a different/modified tune first. I think if you can just make your mixture richer (around 12 from the onset of boost to redline) that may make a difference.

    Unfortunately someone else is going to have to walk you through what to do with the Procede. @Tzu seems to have a good idea about what you could try.

    53k miles is not really a ton to have on a modern car.
