New to tuning: custom tune by shop or do it myself?

I assume the AT is 7 speed on my 08 E93? Would that matter? I selected 6 tried, error, then 7, tried, error.

I had issues connecting with my MHD dongle last time I tried, I ended up plugging in with a k+dcan

I am not flashing, trying to connect for the first time. Now I am getting:

"6-Speed transmission does not support ENET-WIFI Adapter"

You have the orange dongle right? not the black one?

If you look here https://www.xhpflashtool.com/connect_diagram/, it's says MHD WIFI is supported.

However if you go here, scroll down a bit, you see: https://rbttuning.atlassian.net/wiki...ct+to+your+car

"ENET is only available on F and G-Series vehicles. There is no support for E-Series cars with this adapter."

UGH!

Right, Orange

Tried again with phone in Airplane Mode. It immediately told me to turn WiFi on, I did...it worked this time. Bizarre. You have to first start off in Airplane Mode, I guess.

Did stage 1 xHP Flash. WOW you guys weren't kidding, I can notice a difference right away.

Duuude don't waste your time with stage 1 or 2. Just go straight for stage 3. It has more features including the throttle blip. And you can use the custom settings to make it as aggressive or comfortable as you like.

Car has been at a German Performance shop getting down pipes installed. I shared the MHD logs with them. They state there is no fuel issue, that there is a boost leak in some of the wastegate hoses, they will replace them while doing the downpipes. Overall the car checks out very well.

Have you asked them for an explanation on why LPFP drops so low below 50 psi?

Do a log afterwards.

Yes, they said it's the sensors and MHD software. They were not able to reproduce it with their diagnostics. And yes, I will do a log again.

This shop came highly recommend from 2 friends who race Porches and BMWs, let them do all of their work and have much deeper pockets then I do :-)

They work on German cars exclusively, with the bulk of their work being tunes and race cars. I trust them. I'm picking it up in a bit, I will get more details then.

They claiming a stage 1+ map and some "sensors" killing LPFP?

A stage 1+ OTS pump map is a Conservative map, if LPFP crashing on that, then it could be on its way out.

This is what they said

Gregrobin · 07-25-2021, 06:30 PM

Went to MHD 2+ today. Still on xHP 1.

You're crazy, xhp 1....but I respect it. Once you go 3 there's no going back.

Gregrobin · 07-26-2021, 07:51 AM

I created some logs yesterday after going to 2+ and shared them with MHD. Their response:

"Intake air temp is very high (bad intercooler or very high ambient temps) - also looks like you have a small boost leak somewhere. "

This is concerning considering I just replaced/upgraded the intercooler. It was hot/humid here yesterday, would that be why?

What was the ambient temperature?

Gregrobin · 07-26-2021, 10:47 AM

Where I live it's in the low to mid 90s right now with very high humidity.

That's around 35 degrees C, ambient temps pretty high so that might have caused your corrections.

Have you got links for the stage 2+ log?

I shared the log from June, post intercooler install, with MHD and shared my ambient temp. They said the intercooler is ok now.

Yesterday's log: https://datazap.me/u/gregrobin/greg-...og=0&data=3-22

IAT's are getting quite high, although the corrections aren't crazy high just multiple ones upto around 3 degrees, not the end of the world, your high ambient temps won't have helped.

If the IAT's aren't dropping after the pull, stage 2+ might be too much for the FMIC, you'll have to monitor it and see.

Which FMIC exactly are you running and do you have catless or high flow downpipes?

Your WGDC reaching 80+% which indicates possible boost leak.
