Shiv/Brett:
Good Morning!!!
Guys let me give you a few tidbits that I noticed.
I pulled the Xede and gingerly braced it against the footwell.
1. When I toggle the ignition to on I get the flashing orange LED which goes to green upon startup.
2. If I accelerate in anyway above 1.0bar the engine cuts out (seems to be registering an over boost situation)
3. If I floor the accelerator and it "bangs" up again 1.0+ bar the light will turn orange. At which point I can't get anything over .8bar (almost like a limp mode). Once I decelerate below 2000 rpms the light will go green again.
4. If I accelerate and just exceed 1.0bar the engine will cut out, but the light will stay green. If I accelerate and hit 1.0+bar again the engine will cut out but the light will stay green, etc, etc.
5.) If I stay under 1.0bar with a green light the EVO runs fabulously!!!!!!!!!!
Any thoughts?
Thanks very much for your help.
Regards,
JS

I didn’t get to do too much testing because I drove it home low boost and turned it off. I restarted normal – 0 time in the acc position. Just key in and crank (like always). I was back to full boost. I will check my firmware version and let you guys know.
Things I would check…. (Especially EVO-Bandit)
When having to put the key in the acc position for extended time I would look for a voltage on the ground. Putting the key in and engaging the cars electrical system may be charging the car and correcting back to normal electrical flow. I have had problems similar with motorcycle electrical systems with after-market chips. I would really look at sub-woofers and capacitors that may not be grounded correctly or power wire for them off the battery that may have been vibrating and skinned the wire just enough to put power on the chassis.
My final bit of useless info-
The chips and resistors just modify the voltage. The Xede doesn’t generate voltage is just takes what it is given and massages it putting out better levels to increase performance. I have seen that the culprit in 99% of the times that I have seen problems like this are “bad voltage/ground in = bad voltage/ground out. A +12VDC lead is relative. You need a ground back to the souse to use it. A +12VDC lead with a +12VDC ground and the Xede will work like a broken toaster (nothing).

Thanks for the response and for helping a fellow Cajun.
I’m not 100% sure I understand what you are saying. I’m not an electrical expert, by any means. I don’t have any after market stereo equipment, so I’m not sure this would be an issue. Do you think a grounding kit may aid the condition????
Thanks again.
If you have not modified the cars electrical systems (radio, speakers, alarm, neon,...), then you shouldn't have to worry. A grounding kit (factory or DIY) in the engine comportment would not make this happen unless you hooked it up to the positive side of your battery. In which case you would be going thru batteries by the truck load. The factory grounds (black wire with yellow stripe) suck! This is just a quick fix for people that may hve some junky speakers or had a bad install. When pulling power wire from under the hood to the trunk there are a great deal of places to "skin" the wire.

XEDE died today!
OK guys,
I have to vent. Today the XEDE died on me. I started the car this morning to go to work. The EVO fired up right away, green light – power was good, boost was good. I left work early today and went to get a late lunch. As I left work, I started the car; everything was fine – green light on the XEDE, no problem. After lunch I got back in the car, the XEDE would not power-up, nothing. I tried my trick of leaving the key in the “acc” position for 20 seconds, nothing. I tried again with the key in the “acc” position for 30 seconds, nothing. I tried for 1 minute, nothing. I drove the car home limping along at 10 psi. When I got home I tried everything I could to get the XEDE to power-up. I tried disconnecting and reconnecting all the plugs, both on the XEDE and on the ECU. I tried changing the grounding location – nada. It was a really hot day today in New Orleans, which seems to make the condition worse (for whatever reason). This is becoming a major aggravation. I feel like ripping the dammed thing out and drop kicking it back to California. I need advice from Shiv or someone at Vishnu on what my next action should be.
Please advise. I will PM you my contact information.

I feel for you. Shiv already assured that he would replace defective units straight out. Pull it off and send it in and let him look at it. It would also be good to have it there when the guys from Chiptorque are there. Save your tuned map so you can reload it.

Crazy XEDE behavior...
Thanks for the concern. I PM’d Shiv and he responded immediately. Something crazy is happening with either my car or my XEDE. Although, none of the other electrical devices in my car have a problem. Right after I PM’d Shiv, I went downstairs to see if the problem still persisted. The car had been sitting for about 40 minutes at this point. I put the key in the ignition, started the car, and had the green light again. I went for a drive – boost was 20 psi again. I don’t understand it. As soon as I got back home, I shut the car down, and then tried to restart – no green light, no orange light, totally blank. I could not get the XEDE to respond no matter what I tried. I’m going to remove the XEDE and send it back to Shiv on Monday. My fear is that they will not be able to duplicate the problem, since the unit seems to work intermittently. On a positive note, I can’t stand the thought going back to the stock computer, even for a few days. When the XEDE works, the performance of the EVO is light years ahead of the stock set-up. I’m really anxious to get this working. This issue is perplexing. I’m still going to order a grounding kit, as a precautionary measure.

Like I said, I'd really like to get my hands on your XEDE since it seems to a shining example of the power-on problem that few have been noticing. With some investigation/testing, we should be able to see if the problem is the XEDE or the harness. Once we find the problem, we'll call it the Bandit fix to commemorate your participation

I got mine about the same time you did. Mine is barely 4 weeks old and works like a charm. (knock on wood). Seems to be a sporadic issue given that it affects various build dates. My guess is the harness. You'll be rock'in and roll'in again.

Sad day...
Shiv and the gang at Vishnu,
I pulled of the XEDE today and sent it to you via UPS. You should receive it sometime Wednesday. Please let me know when it arrives. Please, Please, Please get it back to me ASAP. I feel like my car is driving under water without it. When you get used to the power, it's difficult going back to the stock computer. FWIW, I really think it's a faulty harness.
Thanks.

If anyone is savvy with fiberoptics in here (i sure as hell am not), id imagine you could get some sort of tube that is somewhat reflective on the inside, and just run that tube from the light on the Xede itself to somewhere of your liking, so that the green or orange light would just bounce and reflect its way up the tube. . . or something like that
