Terry any plans to get a X3M or X4M when it comes out to get a jump on S58 tuning? It's looking like a X3M will replace my M3 when my lease is up in December.

I wouldn't be surprised if they wait, since SpecialtZ only has a RWD dyno. ;-p

I would imagine they will be happy to take a customer car to to early development. But from a long term development standpoint there will be too few people buying an X3M to justify that as a long term company car. I am sure they will order an M3/4 when available, as that will have the most people who will have one who will also likely want supplemental and supporting mods.

I just placed order for X3M Comp

Drove M5C and X3MC back to back, there was no impression left with the M5 but ton with X3MC coming from a 600WHP Full E85 M3

We're actually working with a few people on the S58.
Once we have a beta system running you we'll post the results and ask for a few early adopters

MarinoB · 08-12-2019, 01:28 PM

Any update or progress on S58 tuning?

Stock Log

Stock run. Had to hit the brakes right before the 1/4 mile which killed the mph. Should run 117mph off the brakes. New engine is strong. This is a race weight of 4435lbs + 210Lbs = 4645lbs. Not bad. Actual DA was 4100ft.....not the +6000ft Dragy shows.

Do you have Dragy in your glove box instead of front windshield?

MarinoB · 08-29-2019, 05:29 AM

I've seen some posts on Instagram from Fuel-It about running a JB4...any info on that?

Never tried it in the glove box. I want to be able to see the blue light.

Terry @ BMS · 08-29-2019, 10:17 AM

We have a JB4 BETA in the works for the S58. So far Fuel-IT's X4 has run 11.08 with it.

Another week or two of testing to do and then we'll launch a public BETA for it.

Yep windshield is best to get Satellite signal asap and accurate readings

luchocamp · 08-30-2019, 05:19 AM

OMG 10.88@126mph X4M just E38 and JB4...
Way to go !

Nanometer · 08-30-2019, 10:38 AM

Wow, this is looking like a great X5 50i replacement! Anything in the 11's is fast... sub 11 is just unbelievable. Can't wait to see more results.

onfire · 08-31-2019, 09:04 AM

Another pass but did not have to brake before the 1/4 mile. 118MPH !!!

onfire · 08-31-2019, 09:07 AM

The calculated DA by Dragy is jacked up. 6031FT calculated - 2067FT MSL = 3964 FT......the 3964FT is much closer to my weather stations. Dragy is adding the MSL back into the equation incorrectly.

Terry @ BMS · 09-01-2019, 01:27 PM

Steve got theirs in to the 10s with E30!

We'll be adding the JB4 BETA to our site shortly.

I am super interested in this. Where is most of the talk happening on s58 development? Having a hard time finding people talking about it on the usual forums. If this thing can be flashed to 100% e85, it could be a 130mph suv with ********* and a tune. I would buy it in a heartbeat.

We're already in the 10s@126 on mild ethanol blend.

paradoxical3 · 10-07-2019, 10:34 AM

Do we think that like the S55 it will be able to run full e85 with just a flash?

Fuel-IT is still evaluating the fuel system on the car, we'll see what can be worked out once the back end flash can be added too.

paradoxical3 · 10-10-2019, 05:24 PM

Well, I'm working a deal on one as we speak. I miss my old X1 that I trapped 117mph with.....My M2 is fun, but it just can't make that kind of power easily.

130mph trap with AWD sounds like a nice daily to me.

Agreed! I wonder what the tow rating is

luchocamp · 10-11-2019, 02:18 PM

the important thing is how fast you will arrive with the towed car
