Hey Guys,
I have just had a Vishnu power upgrade installed on my 8 week old 335 coupe from a very reputable tuner here in Sydney however they didn't seem to know what type it was, V1, V2 or V3. (Maybe due to the fact they specialize in Nissan's, Mistu's and Subaru's)

Is there a way that i can tell myself?

Pre tune it was 271whp and now 322whp.

Thanks for any help.

IIRC, without getting into the ecu area you can't tell. You can tell with amount of looms

You should of asked them. It's most probably V2 since V3 was just released. You can tell the difference between V1 and V2 by checking to see if the rear boost control solenoid is bypassed. If it is then you have V1. If not then it's V2.

A reputable tuner should know, as they would have data logged boost etc during the installation

Check the solenoid's, if one is bypassed then it's V1.

If not it's likely V2. You could only tell if it's V3 by the wiring in the ECU area but V3 has not really been released fully yet so I would doubt it.

I assume you have data logged using the proceed reader software, if so then this should tell you what map you are running.

Out of interest where did you go in Sydney, I've had my proceed on my 07 sedan since new (12mths) running around town.

Thanks for the help, i'll be in touch with them again.

WOPALX - I had it done at CRD in Silverwater, they also tuned the 335i that won the 12hr Bathurst race.

Is the rear solenoid bypassed? If not, the most likely V2. If so, then most likely V1.
