Overall great experience. I'm on fbo, midpipe pure 800 w/DS 2.5 as well Sutphin transmission tune, great guy as well. Anyone with an zf8 needs to get his tune.

Doug did a good job on my tune too at least the ethanol maps are AMAZING! He did the flexfuel map for me as well. He has excellent reply back times and very responsive when help is needed.The 93 octane map always have corrections and boost not hitting target but it serves the purpose. I'm almost always running e40-e50 anyway. I'm running xhp stg 3 which I love. What makes Suptin tuning maps stand out for you?

[blacksapphire440i]

Xhp stage 3 vs Sutphin’s racing map is a huge difference. I would say xhp stage 3 is more on the tame daily drivability side while also being a 7/10 on the shifting speed and performance. Sutphin’s trans tune (his racing map) is much more crisp in terms of the shift. It really feels more like a dct than anything else. When you start doing 10-50% throttle pulls going through the rpms the shifts are insanely quick and much faster than the xhp stage 3 OTS map. You lose a bit of that smooth and tame daily drivability but that is to be expected. I would rate it a 9/10 for shifting and performance speed.

It was just slow to build boost and seemed like it was hesitating through the rpm range. With Odin, it builds boost quick and is very linear until redline. I can attach some logs once I have the final revision.

Just want to share, the post has been updated with the final logs and am extremely happy how it turned out with Odin. I would definitely use them again if given the opportunity.

I’m on revision eight I believe with Doug. It’s been slow going, as we started in May, but then my car was laid up for a couple months due to the transmission being built. We had to scale back the boost a bit, as I was apparently running out of injector, so car was throwing codes and stumbling sometimes. It was moving at 7.0-7.1 60-130. Now I’m at 7.3 in so-so DA, so we’ll see what’s left in it. Car is running smoother. Does anyone know how much we can gain from port injection? Getting to the point of diminishing returns now for sure. I figure $4300 to upgrade the intake manifold, 2k for the port rail, injectors and controller, and then another $800-1,000 to re-tune.

Thanks for that explanation. Have you tried xhp true manual mode? I'm really liking it. My car pulls harder with it but I get torque limit 2048 also. Doug was able to remove the limiter on a couple maps which made even more difference in torque. The only thing is I have several maps I like to use from time to time. It would be nice if MHD would add the remove torque limit 2048 tick box option in the next update. They did that for the e90 group. I wouldn't dare ask my tuner to revise anymore maps after all the work he's already done.

You could try the new dorch stg 2.5 hpfp and xdi fuel injectors and stay DI. No port needed. But then the question is do you want to spend a ton just for a few more psi. Actually, I may have assumed wrong. I'm running 29-30psi throughout the rpm range on DAW flowmax 2.5+ on stock injectors which are probably nearly maxed out. For me, it doesn't make sense to upgrade injectors and hpfp because I'm making over 600hp and dont need the additional wear, tear and cost associated with upgrading fuel system again and adding more torque. I say a few more psi because Doug said 33psi would probably be a safe limit for the transmission. I'm already making a lot of torque and the car is FAST. It really depends on what psi your running now and your goals as to whether spending more money is worth it.

I was experiencing the same 2048 torque limiter when I was doing dyno runs of my car. I would always be doing 550/560whp and 490/500wtq before doug tried to remove it and although my car didnt like being on the dyno the max torque I did was 614wtq before the car kicked itself out of the powerband. I also think this was due to the MHD app updating which caused issues with people who had the BRAP option off (which later got fixed) but that would be nice if we could take off the 2048 torque limiter for good on our maps.

will try out true manual mode as well, thx for recommendation

You should be able to do 6.5s-7.0s on a built trans and on a Pure800 with DI only if you wanted a kill map. If you were to go port I would see you making an extra 50-100whp depending on how far you want to take it. You should be at a solid 650-680whp (conservatively) and 650-670wtq (since you are built trans but be careful about the pistons/rods) no problem with a semi pushing it tune. Maybe that would be 30-32psi and 16 degrees of timing on E50... Maybe 30-31psi / 17-18 degrees on full E.... Keep us updated though!

I wonder where I would be if you are doing 29-30psi with doug as well.... I'm currently boosting 25psi mid range to 27-28psi uptop with timing at 15.5-16 degrees... Car is fast but I can tell there power left on the table

That 614wtq is impressive with the boost your running. Seems like you should be closer to 600whp with right intake at 28psi. Maybe DA plays a role in it? So, it sounds like he was able to remove that limiter which is good. I had the brap problem too.

No problem. Let me know what you think about true manual mode. I didn't expect any straight line power gains. It feels like the wheels are unlocked and more able to spin freely as if braking intervention is less.

I posted on MHD Facebook and Instagram a request for the 2048 torque limit check box. I feel like the more people that request it the better chance we'll see an update with it in the future. So, get the word out.

Yeah, there is a noticeable difference going from 27-30psi especially if the timing doesn't drop much.

I wonder if I can just go with the injectors and then re-tune for some gains? Sucks these OEM injectors only have a few k on them. The car is quick as is, but with the built trans, I might as well push it a bit more.

I agree. I would at least go for 30-31 psi or whatever the hpfp can handle. That's probably going to be the next limiting factor. My hpfp does good in temps above 70° on e50 but it may dip when boost initially comes on under 70° with 30psi load range. So, I'll probably run e40-e45 when it's cold out.

I ran out of injector above 30 psi with my DAW DS2 setup on e45 … kept boost at 24 psi on windup so the HPFP wouldn’t crash and then from 4500 rpms onwards 29-30 psi with 14 timing up top. Flat 580 TQ and made 615 whp with 600+ all the way from 5K to redline.

Problem is going port or upgraded DI gets expensive fast and tough call for us folks in the low 600 whp range where it’s fast and fun and we aren’t breaking shit!

[B58togo]

^^
Yeah, it’s the law of diminishing returns. That first 100 whp was only a grand or so. Another $2500 for injectors/re-tune at this point is a tough call. Not too much I run into around here can keep up as is, but with the built trans I’m tempted to keep going.

Well said! I’d say keep going, but that’s easy for me to say. Keep us posted.

Yup as tempting as it is to push 600+ (more towards 700-750whp) it takes another mindset than just doing a HPFP and turbo swap

Yeah at 650-700whp we are going to worry about our tranny. I only recently upgraded from the GC to DAW and so a new turbo simply isn’t in the cards anytime soon …. Car is a daily driver and I should really be happy at low 600s where I’m at… but this shit is addictive!

Can you maybe share a log of your 93 oct tune?

Giving this thread a little Kickstart as I have a daw flow max 2.5+ and ds25 sat in my garage waiting to go on.

I have a dorch zetronix flex kit on there now and a ds1 running mhd stage 2+

With that in mind I'll probably shoot straight for a flex map after I get it installed and running.

This Doug fella seems like a good bet so I'll contact him.

I've reached out to a few tuners so far with varying success. Cd919 was helpful and stimikey hasn't replied yet.

[thormessiah]

Recently purchased a 2021 BMW m240xi, once I get the Femto unlocked I’ll be getting a custom tune and seeing what I can get out of this thing. I have a Diann mid pipe and exhaust on the car already, and am waiting on an Intake from Dinan as well a dorch 2.5 and Daw Ultra R.
