Hey guys, A friend of mine has the exact same engine and ecu as mine. Its a Golf 4 GTi 1.8T AUM Manufactured in 2001 with a Bosch Me7.5 ecu. Information about the ecu: VW Part number: 06A906032HJ 0002 Bosch Hardware number: Bosch Software number: Problem The pre-owner has chipped the ecu. He asked me if I could reset his ecu back to stock. I have found a original.bin file for this exact ecu, even the checksum is correct. I can read his ecu, but I can't rewrite it.

Feb 14, 2017 - Its a Golf 4 GTi 1.8T AUM Manufactured in 2001 with a Bosch Me7.5 ecu. I've tried MPPSv13 and NefMoto Software, both can only read it but.

I've tried MPPSv13 and NefMoto Software, both can only read it but they can't write. MPPSv13 error: 'General Reject' NefMoto error: 'Sectors have to be rewritten, do you want to continue?'

=> 'Yes' => 'Sectors successfully deleted! Do you want to rewrite?' => 'Yes' => Writing error. So I had a bricked ecu with data on it, but without sectors. MPPS could restore the sectors and now everything is fine.

But why can't I rewrite it? The checksum is correct and I even tried pulling the dash fuse. Thanks for help! Posts: 21 Joined: Tue Jan 03, 2017 1:49 pm Location: Germany. On newer ecu it's possible to lock obd write. Don't know if it's the same here, but I'm afraid you will have to write it by bench programmin found this on another forum: 'looks like ecu has tuning protection, rewrite 95040 with this file and then rewrite your audi1.ori after, you can write to the 95040 in bootmode with ktag or you can use the dos based me7 95040 with any kkl cable, but in most cases I just lift the chip and put it in eeprom reader' or try boot mode: Posts: 16 Joined: Sat Nov 01, 2014 5:24 pm Location: UK.

Sorry, the picture upload didn't work somehow. The problem was an anti-write-sockel for the flash chip. The first tuner did this. Sorry, I was inactive quite a while. I was learning how the ME7 ecus work on other forums (I noticed that here are much diesel tuners).

Now I understand the ME7 perfectly (every car I tuned has now over 200+ hp), now I want to understand EDC XX ecus. If you guys could help me tuning a diesel I could explain you everything about a ME7.

The purpose of this page is to give our readers a insight into a 1.8T remap, what it is, a brief analysis of how it works and the different types of remaps that are available. It offers a more in-depth explanation from our Introduction The 1.8T engine is fitted with two main types of ECU’s that are manufactured from Bosch. The early models, such as the AGU/AEB came with a Motronic 3.8.3 (M3.8.3) ECU which is used in conjunction with a cable throttle body. This is a easy way to tell whether you have older or newer style management. The later models, from ~year 2001 onwards, came with Motronic 7.5 (Me7.5). The Me7.5 ECU can again, be split into two main types; this goes off the fuelling method to what the ECU has been designed for by Bosch. These are narrowband and wideband type.

Also unique to the industry is a built-in section of launch fiber to eliminate the need for a separate launch box. Yokogawa offers AQ7275 OTDR models to suit your changing needs: • Wide Range of Modules Available • Enhanced support of FTTH to Metro, Core Network • High Dynamic Range (45dB) • Short Dead Zone (0.8 m) • Optional built in Dummy Fiber.

AQ7275 Models Sorry This Model Discontinued Please call to see if we have any refurbished or demo units available The AQ7275 is one of the best selling OTDRs in the world.

Why a 1.8T remap? When cars are produced by the manufacturers, there are whole host of different criteria that they have to meet, such as emissions, drive ability, quality of fuel used; for example 95RON and 99RON, component longevity and safety.

For these reasons, standard cars are set-up to meet all of these for your average driver who has no intention of gaining a few extra ponies out of their car. Once we look for performance, many of the original manufacturer intentions can be thrown out the window such as emissions, fuel quality and length of component life. This is because components are designed to cope with certain power levels so once performance is increased, some may experience shorter lifespans. Now the boring bit is out the way about how stock ECU’s were intended to be setup, the main reasons for wanting to get a remap is the additional performance offered by means of altering fuel, boost, and ignition timing maps inside the ECU to give optimal performance. A remap will give higher peak power and torque (for those wanting to discuss their cars performance down the pub) and most importantly, and a crucial area to look at, is greater area under your torque and power curves, which will give much more performance rather than focusing mainly on higher peak numbers. A good note to remember is higher bhp/torque isn’t always necessarily better, or mean you will have a faster car than somebody with 25bhp less. This will be because the car has greater volume of power at all RPM points rather than a car with less power across the entire rev range, but has higher BHP at the redline.
