What tune are you running on your x5m

Engineering approved the supersession for the IAM, so the customer can be assured about using the 8165 if the 8179 is no longer available at his parts store.

Stock vs tuned.

Velos barely even approaches 500 though (just for what it's worth, I have a Velos tune).

I think that getting 500whp +/- on a tune with stock hardware seems pretty normal. Which is a good bump in power. The s63 is pretty highly tuned stock and bmw didn’t leave a lot on the table for gains with the stock turbos.

All tunes are going to do about the same gains. In the tuner market usually everyone purchases a base tune from one company and then changes the maps slightly and rebrands it their own. There is usually only one or two companies with the software engineering and computational facilities to brake the encryption, re write oem code and make what’s called a base tune. The companies we call tuners don’t have software engineers and encryption experts in their staff. So they buy a base tune license from these third parties and then slap their own logo and map tweaks and call it a day.

So all the tunes should perform similarly as they come from the same base, have the same code and run on the same hardware with tweaked maps.

Spoke with Frank Smith. Will be going to his shop for a tune in the next few weeks. Along with the tune, we will be installing a catch can setup that he recommended.

Hopefully I will be able to get a base run with my Velos tune to see how different the new tune will be, if it all.

Its been to hot to test here in AZ for past week but late tonight its going to dip down under 90 finally, will test in exact same road I did previous tests on the draggy as temps will be about the same (mid 80's). Will post results tomorrow morning.

Idle quality is better so far with the new Bosch plugs

I will be going to Tucson in a few days which is approx a 200 mile round trip and great to test mileage as its level and straight 90% of the way.

Running a JB4 as well? Might or might not be unrelated but I have this same issue...until I switch JB4 maps.

On your X5M or your M3? You're muddying the waters if you're talking about your M3.

What'd the DME custom tune cost ya? I'm guessing most here are running canned tunes that range in price from $800-$2000 and they're likely all the same tune. I've yet to see a true comparison between different vendors and "their" tunes vs just being BR tunes with a slight tweak.

I tried running E30 and got tons of throttle closure errors and maxed out the adaptations? so I stopped using it. I'm running two step colder NGK plugs based on NGK's own website stating that anyone doing mods should go down one step per every 75hp added. I haven't checked MaximumPSI's prices but Terry at n54tech had the best pricing at the time.

I run about 4gallons in mines and mix with pump or race gas or all 3 together.
Tune i got for a good price im good friends with moe dme

^ This. Unless it's truly custom tuned on a dyno w/ fuel maps, it was discussed YEARS ago on the M5 boards that all these canned tunes are nothing more than a BR cracked tune and then each "tuner" slaps their name on it.

4-5 gallons based on our tank size is E30..saying you're running E85 implies you're running a FULL tank of E85.

I've spoken w/ Moe as well when I was using an Aquamist meth setup before switching to JB4 as a controller. Still curious what you paid though and if it's truly custom or just canned. Did you actually take the car to him, strap it onto a dyno and he sat there w/ a laptop adjusting fuel tables AFR's, etc?

I myself am running a Halim/HCPerformance Stage 2+ tune that I was able to grab for $800. Unfortunately he's since moved way beyond out platform, not verbatim but he compared our DME's to using MS-DOS vs Windows 10 on the newer cars so I can understand why he's not interested in working backwards. Nevertheless I plan on swapping S63TU manifolds and turbos this fall (already sitting in my garage, ceramic coated and all) but I need a REAL tune, not a canned flash w/ a little tweak.

Yes we did... well i wanna do pure turbos in the summer but i no the trans will only around 680-690 700 is pushing it and i wanna run meth on the car but still Debating if it's worth doing it

[m5james]

Noted...I'll have to reach out to Moe again. I agree the trans and rods are our weakest points. I'm at 135k now and had to replace the trans last year...it would just shit the bed and go into a hard limp mode on launches. Rebuilders wanted around $3500 but I was able to find a used one with a verified 11k for $1400 shipped to my door, then I paid DUDMD (local to me in Seattle) to flash the VIN into the trans so it'd actually go into drive. DI engines love meth, we don't really have a good options like the S63TU or N54 in terms of running normal style fuel injection sandwich plates between the intake manifold and block, so meth it is...it's cheaper than running race gas and has all the benefits of cooling the intake AND washing the carbon off the back of the valves. Look at S63TU M5 threads and they'll confirm it. From what I last read we damn near have to drop the engine to remove the intake manifold for walnut blasting so meth is a good daily option.

What i hate is that u need to run a jb4 and tune again to make more power but yes meth is does do a good job on cooling and cleaning i had it on my 335i

[m5james]

This was a few years ago but I tried to get MHD to throw us a bone but they weren't interested. MHD on our 535xiT was night and day while being SUPER cheap, which makes me hate these $1000+ canned tunes that have a rediculouso $ to HP ratio vs a $150 MHD tune. The JB4, even though all but forgotten about by Terry, still has it's perks. I turn it off once in a while but then I'm like...why If I can find a tune that'll make the JB4 obsolete, I'll do it, but that doesn't seem to be the case.

I'll have a comparison on a canned tune vs dyno tuned next week.

I am noticing the transmission is now limiting power pulling boost, didn't notice it until I was studying the g force graph on the draggy then watched a replay and noticed boost was being pulled, then added back in later (I have twin boost gauges in the truck, one for each bank). This further complicates things. I wish XHP would finish their work on the transmission so I can remove the torque limiters.

As of right now, indexing the plugs isn't going to make night and day difference but rather just a very minor one which is what I assumed but had hoped for a little more difference. Probably worth something like 10-15hp, which is very hard to notice on a 500+hp 5300lb truck. Will continue to do more testing but right now I would say its only worth it if you want to Max out every possible drop of power and performance.

Going to hook up my jb4 finally for some real data logging too.

I am about to finally hook up my jb4 to add a bit more power on top of the stage 1 ESS tune. How has your been running, any issues with the install or drive train errors?

Keep us updated on your results. I may go this route as Frank Smith is local to me in MD.
