Sent my ECU on Monday by USPS Express mail from Lincoln, NE to Clackamas, OR and insured it for $1K for a cost of $31. INMotion sent it back postage paid and I received the box back on Friday late morning. The PO say they will refund your $ if your package doesn’t arrive by 3:00 or return before 12:00. Excellent service! I installed it that day and only had a chance to take a short drive. Throttle response was much better and it seemed to be a bit faster overall. Didn’t know what to expect but I think whatever my expectations were, they were a bit high. Remember were only talking about 15-18 more hrspwr and maybe 20-25 lbs more torque on a V6. Check out the exact figures at http://www.inmotionusa.com/website/models.html By the way the company originated in Austria so it has European roots (whatever). I didn’t dyno the car and don’t plan to. It’s not that important to me.
Today I ran a hair over 45 miles in town and on the interstate. I’m not a slow driver for the most part. With that said, in town I have a lead foot and I’m always messing with someone. You’d think at 57 I would grow up already. On the highway I was cruising at 85 to 100 mph for about 35 of that 45 miles. I stopped on an on ramp for the turn around and with the ASR off and power braking the car laid some pretty good rubber and did a little fishtail. There’s the difference! It would not do that before nor would it get 26.6 miles per gal with my heavy foot. With some easy driving I bet you could push 30 mpg. Maybe I’m dreaming. I see that Gunther at [email protected] has an Audi chip on Ebay for $199. Here’s the good part: I paid $190 plus shipping. Before I made my decision I communicated with a dude in Seattle, WA who had his ML320 tuned and he was extatic with the performance. I have yet to get my K&N filter in and some smoothing of the baffles in the air box. That may give me a bit more but I’m not expecting much. I think the next best bang for my buck will be a pulley kit and when my wife isn’t looking a tuned exhaust. After that I would be done.
DIY: It’s not hard to get the ECU out. You just have to be patient and figure out where the “keepers” are on the electrical plugs. Don’t try to pry the plugs out until you know for sure you have released whatever is holding the plug in position. Once you have them released the plugs come out quite easily. On my 99 there are light gray latches the rotate down from top to bottom. There are also “keepers” that slide on a diagonal that hold a couple of white plugs in a smaller silver box on the other side of the plate that holds it and the ECU. There’s also a keeper screw on the right side of that plate that must be removed. Once all the plugs have been removed the plate can then be lifted up and out and the larger of the two boxes can be removed from the plate for shipping. I don’t have a digital camera or there would be pics but it’s really quite easy.
There ya go. I’m a happy with INMotion and would recommend them to anyone. Just remember caveat-emptor! Cheers/David
