trikey Posted August 21 Share Posted August 21 Has anybody successfully programmed substitute fuel injectors for an E 90/1 M57 engine using the Launch creator elite 2.0? My INPA software lacks this particular feature, and ISTA is failing to detect the car after exhausting all possible attempts. Quote Link to comment Share on other sites More sharing options...
Needsnewtyres2 Posted August 21 Share Posted August 21 It is possible to use the engine without coding, although its performance may be compromised. Quote Link to comment Share on other sites More sharing options...
trikey Posted August 21 Author Share Posted August 21 Thank you for your input, Needsnewtyres2. I had already taken that possibility into consideration. Do you think they will adjust to it eventually? Just like many other replacement products such as MAF and MAP, this is also the case.

Needsnewtyres2 Posted August 21 Share Posted August 21 Installing pre-owned or refurbished injectors is a routine practice for diesel engines, and it is often problem-free. (particularly on earlier versions) Quote Link to comment Share on other sites More sharing options...
trikey Posted August 21 Author Share Posted August 21 I value your counsel, and I asked this issue because I came across a passage in the BMW service handbook, namely on page 34 of the engine management section. Adjusting the Injector During the manufacturing process of the injectors, a vast amount of measurement data is collected at precise locations inside the plant. The tolerance limits for injector-quantity adjustment are established and stated using a six-digit number combination. Injector voltage adjustment includes information on the lift performance of the injector. Injector adjustment is necessary due to the distinct voltage requirements of each piezo actuator. An allocation is assigned to a voltage demand category, which is included into the numerical combination on the injector. The ECM receives and processes these data elements. These measurements are used to correct for any discrepancies in the metering and switching efficiency during engine operation. Note: When changing an injector, it is absolutely necessary to perform an injector adjustment. Any more feedback would be much welcomed.

Needsnewtyres2 Posted August 21 Share Posted August 21 Indeed, I have perused that information. Nevertheless, my comprehension is that the injector data is saved inside a BMW database, necessitating a visit to an authorised dealer in order to facilitate its transfer to the DDE.

trikey Posted August 21 Author Share Posted August 21 Fascinating. I will consider this information when the need arises to replace them. Perhaps I might consider using the Launch scanner, which claims to be capable of doing the task. Occasionally, I see the presence of white smoke, which indicates unburnt fuel. Despite this, my vehicle operates smoothly without any oil or water loss. The turbo is functioning well, and the running balance on INPA indicates that all cylinders are within the specified range. The Maf is also within the expected range. I assume that there may be a leaky injector, but I want to do a leak off test to confirm. Overall, this issue remains quite perplexing.
