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. |
| Serial nr 13031 M60 PnP unit sent out in 2017 (when M60 was experimental). |
| 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. |
| All outputs work when in testmode, all fires individually. But when enginge is started 2 cylinder do not run correct (logs and config must be investigated in such case, with logs, config, install details on separate, editable, thematically organized page - necessary for installs and especially required in case of problems ). Dead on idle. then runs in on mid load, then dead again on full load. |

I will send the first 4 units in one package because of limited insurance.

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. |

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. |

* Unfortunate batch made with fake MAX232 that tended to develop serious problems in days or weeks also depending on the RS232 port voltages used with it - yes, nonsense that they fake-manufacture such chips with bogus design, luckily only a small batch was effected and extremely annoying but fixable and not effecting any later batches. Most of the problems seem to be related to the ill-fate 2017 fake MAX232 batch. (which cannot repeat, of course). |
| 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. |
| I will send the USB adapters also, the first one was used on the first unit, the other one on one of the others. But both adapters seem to be dead and I tried it on another broken unit, and they seem to have killed that unit as well. Unit 727. |
