“sad though, takes a thief less than 30 seconds to steal a beemer, but a guy with the key can’t get it to start!!!!”

Sounds hilarious, but it is tragic at the same time because it is true.

I guess there are very good techs working for thiefs… or very corrupted inside employees giving out the information. I can not think of anyone else knowing the codes better than the manufacturers… just saying.

Back to the original question, the problem is that the chip is compatible only with 1994 and 1995 models. 1997 models do not have chips like this, either electronically or physically.

If you jump the two wires in the EWS module, you will only enable the crank part, but the part of the program that disable ignition will still be in the original chip programming unfortunately.

Disabling the cranking motor is only a part of the protection of the EWS system.

I am sorry I can not help, as we are not working with OBD-II models (1996 and later).

If you cut the wires 1 and 3 do you still need to completely disconnect the EWS.

I bought a used dinan chip and now my car wont start with the stock chip also.

I am Marvelled with this , so that means according to Jerryvan Rosado if you cut wires 1 and 3 on the EWS you dont need the chip at all is that right Jerry .

Thanks for your comments.

It all depends on many things, like any other modifications that the car may have, that are in favor of the program in the chip. For example, a chip that increases fuel, should not be installed in a car with bigger than stock injectors, unless there are other modifications to work with that, like forced induction, etc. I know that the above is not necessarily your case, but was just an example.

The most important thing might be the tuner. If the program that the tuner made for the car is not optimized for that car, less-than-maximum gains will be obtained.

As you mentioned, you send a file to a tuner. That means that the tuner did not see your car. I am sure that bigger power gains can be obtained form a V8 engine, but the tuner must have the car present, with it hooked to a dyno and some sort of data logging while doing the changes. That way you will obtain nearly the maximum that the engine can bring, though will cost a lot more than just tuning a one-size-fits-all chip.

One-size-fits-all chips are not bad if they are well programmed, but the back draw of using them is that the power obtained will not be the maximum available, as it is not custom made to your car. The good thing of them is that again, if well programmed, gains of some sort will be obtained (better than stock) and cost will not be too high.

However – the dyno numbers show only a neglectible change in torque and power.
Std. 228 HP and 294 Nm (meas.)
Chip 229 HP and 294 Nm (meas.)
Std. 218 HP and 290 Nm (BMW official).
It seems as if this engine is in good shape making more power than BMW claims.
The torque curves must be concluded to be similar since the variation is only between +/- 2-4 %.
Subjectively it doesn´t feel any sharper or faster – as expected from the dyno numbers.
The rpm limit is raised to 7200 rpm which is of course a little risky – but it sounds good!

From this experience I cannot recommend to spend money on a modified chip for this engine configuration. Does anybody have different experiences or do you agree?

You will hear more soon.

There is no silly question my friend. The only silly question is the one that is not asked.

About the 1995 530i, it uses the same EWS system, and after checking the diagrams, it is also connected to wire #66 of the ecm, so we have not done the test, but being the same everything, it should work as in the 1995 325i/525i. The wire should also be color green.
