ECU Mods again

So far, members have tested Dinan ECU mods with mixed, at best, results. AA Results seem to be a little better. Powerchip (which seems to have a good product for other cars) claims no hp or torque increases with their ECU "upgrade". Superchips claims 25 bhp improvement, but we haven't heard of any member testing this. Lastly, DMS (from the UK) claims a significant improvement to 548 bhp and I do not remember whether anyone has opted for this. Their downside seemed to have been that the ECU had to be sent to the UK, but their advertisements say "programming available in the US and other locations."

I hope everyone is passing along the findings of these upgrades.

I was looking at the software tuning from RDSport. I believe member 6speed has it and I was hoping he would write a review. His dyno numbers are pretty good; I think in the 460+ rwhp range if I remember correctly. Of course, that's with other mods like SS headers and stuff. He also posted some very fast 1/4 mile times; around 11.96 sec.

6speed, are you there buddy?? haha

I am interested in an ECU upgrade myself. There are alot of board members using DMS that have posted positive results. I haven't heard of anyone doing their own dyno on it though.

For the Texas M5 team...I have two options for us regarding the ecu tuning:

1. Active Auto (Omar) is willing to work with us to tune our cars in DFW. He would have his tech fly in and use a local shop to tune our cars with one of their prepackage tunes for 1) stock car or 2) headers or 3) headers + NOS

2. ESS Tuning is also prepared to launch their E60 M5 tune with us here in DFW. They would also fly someone into town and do a local custom tune for 1) stock car or 2) air intake or 3) headers or 4) headers + NOS

So far I have 8 confirmed names and I think that will increase to about 10-12. Once I have all the confirmations we can discuss pricing options with each tuner as well.

You guys just let me know if you're in for this or not. I'd like to get it wrapped in over the next 1-2 weeks at most, then work on getting a date set.

Regards,

Darren

Hello.

Yes, I have the RDSport software and like it a lot. When I installed the software originally, it was with the headers, pulley., etc... so it was hard to determine what actually added the extra juice.

Well a few weeks ago I was having some issues with the car and the dealership had to wipe out the RDSport software. After I picked up the car, I noticed a diference with the car right away as it was low on grunt that I was used to not long before.

One week later after I sent my ECU to RDSport all is well again and that is the same day I went to the dragstrip to see how she was running.

Again, I like it but I cannot compare it to other software though. If I were to get software again and RDSport was not available, I would probably choose AA.


Cheers ///

So, it seems that RDSport and ESS are additional options. Wonder how we can conclude which of the many might hold the edge. Next week, in Fort Worth, BMW CCA is holding its annual Octoberfest event. Steve Dinan is known to have appeared at these events. Wonder whether others also might be there.

I know that ESS, mentioned in Darren's post, has been a major supplier of upgraded ECU software for other BMW Models.

Rick,

I've spoken to Federico at RDSport and he seems like a good guy. The only challenge is they have no ability to come to us in DFW.

I'm trying to find a way to not have everyone's car down for service for 2 days. Some may have a 2nd or 3rd car to drive, but I don't.

Plus, the ESS option would provide a local tune going forward if your car is ever flashed by the dealer.

I'm not saying any of them are better than the others (yet...give me time to formulate a rational opinion). The reality is all of them, if any good, will get roughly the same results (10-20 rwhp at most).

Cheers,

Darren

$2200 for a delimit and MAYBE 20hp? No thanks.

Thanks for the feedback 6speed.

Does this mean that you had new software installed? If so, do you know what version?
