I have ben waiting for a ECU software. After reading the post made by Hamann 6 and Adam of Kronen. I decided to give them a vist. Adam, told me that it would be possible to do the up grade on this visit. So, why not $1,500.00 compare to others. It took about 3hours. But I'm telling you all , that it is a very good deal for a software. software.
So attention Nor-Cal M5 E60 owners. The place to go for your ECU is Kronen Tuning

Gustav, you probably know me from mbworld.org. I am assuming that you will probably know I only carry reputable tuner brands (brabus, renntech, carlsson for mbz) and in this particular case, i sincerely believe in Singh's ECU upgrade. Although i know baseline and post-mod dyno runs are very necessary to determine the gain on hp/torque, personally i would think the ECU upgrade from Singh is worth every penny.
Give me a few days, and i will try to obtain the dyno sheets.
I emailed Singh on this topic. They have had bad luck dyno'ing M5s. I have read elsewhere that other tuners have had similar issues.
I have had my E60 M5 dyno'd so know it "works" on the dyno. I am considering this ECU and, if I do it, I will get an independent dyno before/after AND do some 0-60 and 0-100 runs with the GTECH before/after. I think it's the only way to get objective data: dyno + street numbers.
It's just odd that, given people's obsession with performance, they don't try harder to measure gains. If the placebo produces euphoria, why question it, I guess.
If the M5 did not come with P500S mode (only P500), I'll bet I could charge $2K+ for a mod that "unlocked the power of the beast." In reality, of course, you just need to press a little hard on the gas to get the same effect for free....
BTW, I don't mean to bash on Kronen/Singh in particular (I will probably buy their product!), it's just weird that solid data is so hard to come by (from tuners in general).
My 2 cents.....I think tuners are either too busy or tooo lazy or just don't have the ability to give us the facts..........to support your product you must back it with data sheets.........thanks Gustav
