I installed my PWM kit on Saturday. There were a few hiccups along the way (like dropping the spray nozzle T fitting down in my engine bay) but I believe everything is hooked up right and running correctly.

I did a few pulls. Got the indicator lights to come on. Seems like it's working right. However I have a few odd things that are happening and I've been searching but can't seem to find any information regarding my issues.

First, after a pull (as I'm decelerating) the meth flow indicator lights come back on for 2-3 seconds and then go away. Not sure what that means.

Second, when I shut the car off the Rev 3 Procede - or at least that's what I assume I'm hearing - makes several clicking sounds (about 6-10 every second or 1/2 second) before shutting down completely.

Third, I'm getting a 11610 code for "Control motor torque limitation". Not sure what would cause that.

log of the poor timing values?

Here is a datalog from last night. Not sure what meth injection flow is showing, but it doesn't appear that meth is actually flowing, even though the indicator lights are on.

[enrita]

your meth flow drops abruptly there must be something wrong with it, maybe installation?

[Tronner]

Here is also a video I took of the meth indicator lights staying on long after the pull. Not sure why that would happen either?

Something isnt adding up here. Your spraying meth off throttle?

For throttle you should log DBW Throttle.

Your IAT are kind of high too.

Re check your wiring and other aspects of your methanol installation.

Unplug that system right now. If those meth flow logs are accurate you are going to flood your engine.

1. You need to remove everything and reinstall. You do not want flow after you come off the throttle

Hydrolock and catastrophic failure impending. Yank the kit.

I suspect you have something miswired.

Its likely a wiring/ grounding problem. when you have the wiring messed up into the procede it throws those large spikes of methanol flow.

Hell if its not hooked up at all you can ready 50+ flow.

Crap! I can certainly pull the kit, and recheck all my wiring. I can also take pics of the places where I tapped for power, ground, etc. I'm 99% sure I followed those directions correctly, but I'll recheck. Could it have anything to do with using a Rev 2a Procede harness with Rev 3? I did the harness update that Shiv posted a few months ago, but my kit came with the map switching box etc which apparently is not used or needed anymore.

Here is what I know:
The pump works correctly because jumping the boost switch purgest my washer tank no problem. I know the Procede is talking to my computer and seems to be running the non-meth maps just fine. It seems like the 30 amp fuse in the fuse holder doesn't push down all the way into the female receptacle all the way, but it's definitely touching plenty of metal.

What would cause the odd clicking sound I’m hearing near the DME box after car shutoff? It clicks almost 20 times in a row and then shuts off. I’m getting a code 11610 for control motor torque limitation. Could that be something with the relay I put in during install? I know that I put the Procede side female spade on terminal 87 and the one going to the connector on 85.

[Tronner]

I think I know what it is. For some reason I was thinking that now that I have a Rev 3 Procede (but using an old harness) I didn't have to do step 10 of the installation where you wire in the two meth harness wires to the procede. Makes total sense that it won't work without those connected.

Don't they go onto pins 87

You should probably call vishnu to ensure what your running is compatible.

That would be a problem as it controls the meth flow and modulation.

Edit:Step 10 does say if you have a rev. 2 Procede to do that wiring. So not sure about a rev. 3 unit.

Agree with above call Robert at Vishnu

[plague]

you DEF have to wire the two small wires coming from the meth harness. youre talking about the black little wires, one with female head one with male. and you pull wires from pins 17 and 4 from the GREY subconnector (red wires mostly) which should be white and black and those two each get plugged up to the two black wires coming from meth harness... incase you were mixed up? do that and report back. thats what signals meth flow its needed. the only step you can skip is the red power wire being cut and connected to the harness... if you choose too... i skipped it, but we tapped power elsewhere.

[Tronner]

OK, so that was definitely the major issue. Now it seems to be working better. First few pulls the lights blinked on and off a couple of times, now they seem to be on solidly throughout. However, my timing still seems pretty low (supposed to be around 10 throughout the run correct?) and my autotune boost dropped after the last run. Any other ideas? Here is a new third gear log and my user settings:

[Tronner]

Another question would be why my DBW throttle only reads 54-78 at full throttle throughout the pull? Is that normal?

why dont you plot it as well? easy way is to create a template that you ALWAYS use so you start understand it as well. Timing dont look good. What meth mix are you running?
Also add CAN Actual AFR 1 and 2 .
do you have DTC on ? switch all traction control off.

Yes.....78 is full throttle.

I think you are running boost too high on map 1.

What that means is that until meth kicks on and the tune switches over to map 2.....you are running 15 psi on regular gas.

That may be part of your bad timing initially.

Try lowering the map 1 boost value down to 25 = 12.5 psi and see what happens to timing.

Leave map 2 as is.

Plus give it some time to adapt......your DME remembers your bad timing curve and will need to relearn.....so it may take 3-4 runs for that to happen.

[cwn23]

78 throttle % at full throttle is normal reading at WOT, 54 is not

[Tronner]

Here is the same log with AFR and DBW on it. What would make the throttle not read full at WOT?
