For 528 or 540? If you have a 6 cyl BMW (528), Jim may have an reprogram available. BUT there has not been much feedback, if any, from anyone who has actually installed it.

Jim is an urban legend chip tuner from the days you could just pop out the chip and put another one in. He swims on the 3 series board. His chips pushed the performance envelope and gave the best increases in mid range and high end power. They had them for the whole range of BMW's. Better performance increase than Dinan or anyone else. He answers few of his e-mails on this and has never returned my call on this. I've heard this from others & I'm sure he is bombarded with people calling him and e-mailing him so don't take it personally if you don't hear back from him.

Then came OBD-II, what we have now, a system that you could not pop chips in but had to reprogram the ECU. OBD-II is very complex and not easy to decode.

Word on the steet is that if Dinan had not gotten the 540 base code for the unit from BMW, Dinan would not have a reprogram to offer either. The other thought out there is that the 540 is already mapped nearly as agressive as can be and that Jim can't get much more out of it.

Not much has come from Jim for 540i OBD-II cars and don't hold your breath waiting any more. I was told something would be out over a year ago for the 540. Still nothing. His web page has not been updated for nearly 18 months. The latest from his rep, Josh at Eurosport, is that their current project is a supercharger and that a reprorgam for the 540 is back burner. After waiting 2 years for Jim's update I just went Dinan flash. Slight improvemenmt. Added CAI with more agressive Dinan flash and had strong improvement. I missed out on a lot of time I could have enjoyed the car more.
