Back to the wheel speed sensor, does it cause any problems when you pull the front tires off the ground? or is it just part of the data log?

If he pulls the front tires, then it all breaks down and the car shuts itself off. Technology, ya know. ;-)www.realtuners.com - catch the RealTuners Radio Podcast on Youtube, Facebook, iTunes, and anywhere else podcasts are distributed!

If you run the car with that sensor disconnected the default mode is -40* and it'll run rich as hell. Ask me how I know.
With technology I would think you could reset the default mode so it does not run so rich when you unhook the MAT, ya know. ;-)

Sorry to disrupt all the topics of coolness you have going on right now but I have a quick question going back to your power window install. I got the same kit and have a problem with it blowing the fuse as soon as I turn the car power back on. I even went down to minimum config with just one switch wired and it still happened. I pulled the motor leads off the switch for the driver door and it goes up and down fine with the battery off my drill so there's no short there.
Did you find anything hinky with the switches or wiring diagram? I wanted to just use two switches in the console but when I had problems initially I went ahead and wired all 3 in to make sure I didn't make bad assumptions on adapting their diagram.
BTW, I found out real quick how different our doors are when I went to install the motor assy's. I almost gave up twice before coming up with a workable mounting solution. I only have the middle 1/3 of the door behind a panel, the rest top and bottom is exposed metal.Drag Week 2006 & 2012 - Winner Street Race Big Block Naturally Aspirated - R/U 2007 Broke DW '05 and Drag Weekend '15 Coincidence?

A lot of systems default the temp sensor inputs to a certain temp when they read "-40 degrees" but not the megasquirt so far. Frankly I like it that way because it makes things easier to debug. And besides, I've never seen a temp sensor go bad except when it was smashed with a hammer so... it seems to work just fine.www.realtuners.com - catch the RealTuners Radio Podcast on Youtube, Facebook, iTunes, and anywhere else podcasts are distributed!

Car started having the same issue when I hose the engine bay off. The TPS goes nuts until it dries out (driving in the rain has been fine). I simply switched the accel enrichment to MAP and turned off the fuel cut off and ignore the TPS sensor altogether until I see the readings stabilize. It's only happened twice though, and I think it's related to my wiring. If I'm leaving town (~250+ miles) then I take my laptop with me anyways so it's not really that inconvient. I have and have seen people chase ignition and carb problems with a lot more difficulty than I've had troubleshooting weird behavior from my car.
One thing I hadn't thought about, if you're pulling the front wheels using the front VSS doesn't do you a whole lot of good for traction control. If you're into that sort of thing =PEscaped on a technicality.

Thanks for the info!
Bill i really like your car, i think the EFI really adds to the cool factor.

Thanks for the heads up on the overall great kit Bill!Rich

I have to admit that I'm really enjoying having the power windows in staging lanes. It may be psychological but as I'm typically racing solo being able to do some of this stuff this way helps me concentrate.
This week I'm adding a little fan to the trans cooler as I found I was building more heat in the trans fluid than i'm comfortable with when I hot-lapped the car. I'll use it for True Street events, but I may leave if off for Drag Week depending on what the ambient temps are forecast to be this year.
Then it'll get tested here in Tucson on Saturday.Last edited by CDMBill; August 4, 2012, 11:11 AM.Drag Week 2006 & 2012 - Winner Street Race Big Block Naturally Aspirated - R/U 2007 Broke DW '05 and Drag Weekend '15 Coincidence?

I've been thinking about Russel's earlier point about the MAT sensor failure default, and I think I might just put a null enrichment value in at the -40* point to avoid the issue in the future. The issue being a full second loss in ET.Drag Week 2006 & 2012 - Winner Street Race Big Block Naturally Aspirated - R/U 2007 Broke DW '05 and Drag Weekend '15 Coincidence?
