Anyone have a BPM and ESS S/C tune comparison?

[Harry Da Hamster]

What the title says. And difference in performance?

[MFL]

I think most people with used kits go the BPM route, not sure there's a 1:1 comparison.

[W Cole]

i think most people with used vf kits go bpm and used ESS kits go ESS. I have the ESS 625 kit and can't imagine a tune being any better.

Our tuner designed the hardware and spent years perfecting the software you cannot improve on it.

Agreed. 32,000 miles of perfection. Not one CEL, misfire, or even hiccup. Car was a beast making 580+ wheel when catless beating the snot out of so many built cars at airstrip events.

When I messed up and the intercooler pump wire was not connected and I didn't even notice yet attended an airstrip event on a hot day on pump gas. IATs must have been through the roof and the water in the manifold boiling. Yet the ESS tune saved my ass and simply pulled timing to a safe level. Sure the car was slow and I lost races to slow ass cars but who cares I drove home and then diagnosed and plugged the wire back in an BAM...570 wheel again on the dyno.

Getting an aftermarket tune where all they do is play with the tables could seriously jeapordize your $25K motor. Why do this? I've personally seen blown motors from bad tunes on blown M3's at the racetrack and airstrip. People will tell you anything to sell their product. Stick with what it proven.

Based on the number of software flashes we have sold for pre-owned kits, that generalization might not be as accurate as you think.

[Harry Da Hamster]

Yeah i didn't know if people used this as a performance upgrade or just a method of getting a tune for a used kit. Perhaps Mike Benvo would like to comment?

[Beedub]

I'm on the ess tune for my a54 kit.... i see no reason it needs changing, the car behaves like stock really... i think if it ever needs changing, id go back to them. I'm sure another tune can squeeze more power but at what cost?

I'm with you. I bought my SC used and went with ESS for the tune. Why? because who know their product better than the manufacturer?. I just Dyno mine and was not happy with the numbers it put down compared to my buddy with same kit who put down way more. Got a hold of Roman and AJ is working on my file to see why so different on similar kits.

Did you check for boost leaks? What PSI and kit are you running?

[jeff@autocouture]

i would not be using a generic tune for a kit that has already proven itself, stick with what it was designed for

No leaks at all. I got the VT2- 625 on my P3 gauge I see the boost go up to 5PSI. I'm replacing the belt just in case it's streched and slipping on the pulley.

[BrewRifle]

Straight from ESS' website- VT2-625 specs: Boost pressure: 6.5-7 PSI Intercooled. If you're only hitting 5PSI (and you're 100% sure it's installed correctly), then it's safe to say you're near the VT1-550 PSI, not VT2-625.

I'd have the diverter valve checked as well as that all of the velocity stacks are properly seated on the throttle bodies as well as all vacuum lines.

Yeah that's what I told AJ and Roman. I have not have issues with the kit at all just that I finally did take it to Dyno and was hit with this results. 530 PS motor 522 HP, 489 Nm 360 Ft Lb, and 494 PS Wheels 487. You can see in the Dyno sheet. Top is to the motor, middle is Nm, and bottom wheels. The first 2 runs where in 6th gear and the 3rd was in 5th gear.

[squartus]

I thought dynos for this car were usually done in 4th gear?

I do miss my BPM tune, I went with ESS's after i got thier supercharger as it was free and they developed it so who would know better.
BPM tune had much better throttle control, steering and overall options. ESS's is pretty touchy on throttle even in comfort. Can no longer "ride" the throttle crusing up to a redlight and get that nice gurgle sound. Its either gas or engine brake, no inbetween anymore.

Far as who's Tune gives the best power for the kit, or is safer for the engine I don't have a clue.

You can request their less touchy throttle map to be included in your supercharger tune.

This is correct. We have had several cars that we have had custom throttle mapping done on.

I don't mean to highjack this thread but i was hoping some of you with the ESS-S/C can shed some light and help a new m3 owner out. My car has the ESS 625 kit and i finally put it on the dyno and wasn't too happy with the numbers. Finally learned how to use the snow performance meth module and set meth to start at 4 psi and stop at 6. VERY disappointed with the numbers actually . This was on a dynojet and car made 470whp. The car doesn't feel crazy fast either like i always imagined. Dyno was done in 4th gear and all traction off and shifted at 8000rpm. The car did blow some black smoke out of the Active Autowerk exhaust in some of the pulls.

It's pretty hot right now, did you get AIT readings and boost readings? What boost gauge do you have and are you able to recall high readings?

Don't have any boost reading. MY snow performance meth kit has a gauge on the control module and it reads 5-5.7 when full WOT but only at the 5-6k rpm anything below 5-6krpm i think its under 4 psi. Not sure if thats normal.

I did let the car cool down for about 45 minutes before putting it on the dyno.

On the dyno sheet the 2 highest numbers were AFTER shifting.

Car is DCT
it was about 85 degrees out
I don't know when the last owner changed the plugs as I've only owned the car a month. It has 50,000 miles on it now. Seemed like it was taken care of so its possible they are under 10,000 miles old since the oil is pretty clean also. Just a guess..

[Patrón]

Before pointing to the tune I'd recommend confirming boost readings.

[ONE_slow_m5]

For the 625 i think it should be about 6psi toward 6000rpm no?
Is it true thats its linier to the RPM 2k=2psi 3k=3psi 4k=4psi etc.. ?
