Visit Preferences to set your user name Summary of change: Under this Post I will post a list of Units that will be sent in for repairs. Please do complete functionality test on all units. NEW 2018-01-25 ---- I have 11 units in need of repair or return. Unit nr 1: Serial nr 6858. Multiple high current damage, Caused by burnt coil - damage mainboard No comm. Mainbord replacement. VR/Hall 2+6Logic. "2JZ VAG coils, Custom harness" Also add one Missing FET clamp. ... Unit nr 2: Serial nr 9540 Damaged P259 chip and Damaged Stepper chip. Also possible other damage. VR/Hall 8+0 IGN. "Bmw M50 stock coils, Twinshield" Fix whatever is needed. ... Unit nr 3: Serial nr 9332 M50 PnP unit, worked for 1 hour, then just died. Some form of bootloader/firmware issue on reboot. I want full refund on this one. Will send it WITH external MAP sensor. ... Unit nr 4: Serial nr 13031 M60 PnP unit. Never worked right, 2 cylinders missfires. Some form of manufacture defekt that manifests in problem with injector output or IGN output. I am almost sertain the problem is with the injector outputs. All outputs work when in testmode, all fires individually. But when enginge is started 2 cylinder do not run correct. Dead on idle. then runs in on mid load, then dead again on full load. I made a "Patch harness" for this car, and used a stock VEMS 3.8 unit and it has run perfectly after that. Even installed this defektive unit again, and the problem returned. I want full refund for this unit, and 200 euro for the time spent looking for this problem. Spent 10 hours looking for a mechanical fault :( Will send it in with external Map sensor. ... I will send the first 4 units in one package because of limited insurance. ... Unit 5: Serial nr 13039 M60 PnP unit. This never worked. No trigger. This has Manufacture defekt. This is not wired correctly. I have messured it and GND pins and Trigger pins are not where they are supposed to. I want full refund on this unit. Plus 100Euro in handling of this problem and shipping fees and the fakt that I had to stay upp all night to make a patch harness for this car. Will send if in with External map sensor. Do not send any M60 PnP units back to me.. ... Unit nr 6 Serial nr 11151 Damage/faulty 5volt output and possible IGN fet damage and Stepper chip. Damage caused by melted wiring. Vr/Hall 8Ign "BMW M20, twinshield" Repair what ever is needed. Do complete functionallity test. ... Unit 7: Serial nr: 2365 Old unit used with many cars. Memory damage. Looses information when used. Firmware update not possible. Please change mainboard and update with Knock and LCD. ... Unit 8: Serial nr 727 Old unit, multilpe problems, just replace mainboard. ... Unit 9: Serial nr: 14354 I belive this unit was sent for repair prevously. And when I recived it back it was still no com. Just replace the motherboard, and any missing parts. I have used it for parts. ... Unit 10,11,12: Serial nr : 17562, 17797, 17570. All 3 units share the same problem. Broken RS232 communication chip. When connected to USB the units start to draw exessive Amp. Like 0.6Amp. instead of normal 0.15Amp. Unit 17797 was used only with regulat COM port, ans stopped communicating in the middle of the tuning session. These I will not pay for fixing. These where used under normal conditons and all broke the same way. And they do have very close seriel numbers. I will send the USB adaptors also, the first one was used on the fist unit, the other one on on of the orters. But both adaptors seem to be dead and I tried it on a nother broken unit, and they seem to have killed that unit aswell. Unit 727. These 3 failures have cost me in exess of 200Euros in shippings, transport, handling and refunds. I would like to see that amount decucted from the total bill for all the fixing of all the units. ... Unit 13: Serial nr 14236 This Was installed with my custom PnP patch harness for BMW M60. Was tuned successfully and ran for 3 days, then just died and stopped communucating. This was accualy in a friends car and I was next to it when it just died on idle in the depo next to the track. We put a new unit in the car the same day, and it ran perfectly the rest of the summer last year. I dont want to pay for fixing this. Noting was wrong with the car installation since I did it. Fix it, replace the SD card (I will pay for the card) and send it back. ... Please send out the units 2-3 at a time. As soon as they are ready. Send detailed individual cost of each repair to Info at engdahlmotorsport.se ---- OLD: ---- Send detailed individual cost of each repair to Info at engdahlmotorsport.se Ask for return address before sending back, I will change adress 2016-08-30. Please send out the units 2-3 at a time. As soon as they are ready. ---- '''RS232 serial communications''' Please note that '''devices with dual WBO2 (and old devices) have NFET on EC18/pin17 (2nd WBO2 heater), not GND as most new devices'''. * That means RS232 connection with GND only on EC18/17 (RS232 GND not connected to EC36/26) will fail to communicate, or worse: sometimes communicate, but unreliably. (eg. communicate with engine off, but frequent comm disconnects with engine running). ---- Unit number: 4130 belongs to Engdahl/RBD Damaged LM1815. Unknown reason. Also some unsure funktion of some parts. Test everything. Please change it, or change is to Hall if not possible without board replacement. ---- Unit number 11658. Belongs to Engdahl Brand new unit. Burnt Stepper chip due to short in solenoid. No communication after the chip fried. Main board replacement authorized. ---- Unit Number: 8168. Belings to Engdahl Injector channel/channels grounds on powerup. Suspected INJ driver chip damage? Test it and fix whatever is broken. Main board replacement authorized. ---- Unit Number: 2365.
