no start after conforti chip install in '95 CS
 

I tried installing a conforti chip that I purchased with a spare engine and transmission about a year ago. Finally got around to doing the install. Tried to start the car, no start. Put the stock chip back in and car starts right up. Is there anything special about the clubsport electronics like EWS that needs to be reset.
Any suggestions. Also what are the markings on the chip?

Thanks

I think it is plug and play.
Nothing unique about a CS compared to any other M42.

No bent pins? Previous owner could have installed it backwards and fried the puppy.

When I got my Dinan chip the EWS needed to be aligned by the dealer before it would start.

The pins all look good to me. What would a bent pin do? I did install it with the notch in the correct orientation.

Does anyone have an image of what the conforti chip looks like? The "conforti" chip that I have looks like this one. The numbers on the chip are 1 267 356 548http://www.pelicanparts.com/BMW/tech...stall/pic3.jpg

How can I tell if my car has EWS. The car is a '95 CS.

I believe all BMWs starting in 1995 had EWS. I know my 1995 318ti has it.

A bent pin would miss the socket and not make a connection. Bending a pin can cause it to break right at the body making it completely unusable if that pin actually used.

Be careful about not breaking what looks like a resistor pack. I have done that in the past.

If you use a screwdriver, rock both sides out slightly and gently.
Prying it from one side can cause the pins to bend and you don't want to cut any traces below the socket.

According to the number, your chip is for a 1991-1992 5 series.

I don't know anything about how these chips work, but it seems like the wrong car to me.

I take it that the picture is not of your car/chip because the chip number is different...

I'm no expert, but IIRC, there is a difference between what chips will work based on build date, not model year...

If I'm wrong, please correct me, but I think the production date changeover is 11/94... Pre 11/94 is non-ews (possibly)?

Cars from 95 can have two different ECUs. Later year model cars have an ECU that ends with part number- 282. There is a different chip from Conforti for the different ECUs. Compare the ECUs from the two different cars to see what the part numbers are. I think most club sports were produced later in the year, and use 282 ECUs, but I don't know that for sure.

No alignment is needed with the proper Conforti chip. I'm not sure why the dinan chips needed to be aligned, other than the dealer is typically the retailer for this chip.

You could make the assumption that the dealer might want to make more off you by saying the EWS would need to be aligned. I would not put it past them, but in my case, I took the chips home and installed them myself and no start. The dealer confirmed that EWS aligbment would not be needed. However, they were wrong and aligned the EWS and Dinan chip free of charge, so they had no monetary incentive to do the alignment.

my 11/94 318i (not ti) uses a 357 ecu and no EWS, just for reference

FWIW, im not sure thats a conforti chip pictured. Mine had a TMS/Conforti sticker on it..
