Eta ecu's

[ST1G]

I pulled my eta ecu to put a Mark D chip in it I got from Guten Parts and I have a 0 261 200 007

I did some searching and it seams I should have a 027 This unit seems to be from a e28. Will a 027 be better suited for the e30? I think the chip was designed for the 027 but if it will work fine in the 007 then I don't think there is a reason to change it.

I don't know much about ecu's.

The 007 ecu can't be chipped. You need the 027. Here's a link to Rod Paine's 528e page about chip swaps for the eta: http://www.mye28.com/tech/rods_pages/id6.html#ecumod
All of Rod's info is excellent. He actually makes diving boards seem cool....

Yeah, pulled it apart, noticed it can't be chopped. Thanks for the link mate!
