Diagnostic/tuning tool

I was wondering is there a tool you could plug in maybe to a computer check everything thay could be wrong or using it to tune and get more performance. I have the peake thing but thays not much help. I have a 1992 525i m50 engine thanks in advance!

the peake tool is the tool you're asking about.

how is it "not much help"?

The one that I have heard most about is carsoft. However, even it is limited in what it can reveal since our cars are OBDI. On OBDII, it can give live readouts on lots of data points.

Also, our DME's are not "tuneable" in the sense of hooking something up and making tuning changes. I have read about a WAR chip that supposedly has a lot more tuning capabilities. Perhaps you can google it and get some good info. There are some good performance chips out there that give 15 or so extra HP, but that's pretty much it.

Basically, our beloved M50's are pretty much what they are as far as performance goes unless you go forced induction and that's not cheap by any means.

Went from a BavAtuo chip to a Turner. Turner ran circles around BavAuto. Night and Day. BavAuto was hardly anything, novelty at first and then just buyer's remorse.

Aftermarket chip for "tuning"

Peake research code reader or stomp test for diagnostics.

Ahhhh the simplicity of OBD1

+1 There is no useful tuning you can do at home to extract more HP from the M50 than Turner or EAT (Mark D'Sylva) have been able to do. These two chips are generally considered the best for M50 applications. I had an EAT chip for years on my 525iT and was very pleased with it. Miller has been advertising a tunable chip for the M30 engine for years and was working on one for the M50. I don't know if it is available yet. Even if it is, there is not a lot you can do that the professional tuners haven't already accomplished unless you are bolting on forced induction. I think the WAR chip makes a lot more sense in that application.

As far as extracting more useful information than is possible with the Peake tool, there are many users that have put together a clone of the BMW GT1 diagnostic system or purchased one outright from Asian sellers on Ebay. I you want to roll your own, you better have some decent computer skills and be somewhat familiar with both Windows and Linux. If you are not deep into computers, you can buy a turn key system if you look on Ebay. The GT1 is not really user friendly and you will have to spend time learning how to use it. It is the most powerful software available for diagnosing and monitoring our OBD I engines. Look on the diagnostics subforum of another forum for our cars and you will find lots of information.

Ok thanks guys I have that little peake tool and I have a dinan performance chip already in there but thanks for the info
