MHD Stage 1+

Willygbr66 · 01-20-2021, 02:05 PM

Looking for people’s opinions. I know this may have been answered in previous threads and have read as much of the forum around my question.
Have a 2007 335i with 110k on the clock. Charge pipe, vacuum lines, gaskets changed etc. basically looked after most maintenance items and changed accordingly, except injectors and coils.
Been running MHD stage 1 for some while with no issues however am thinking of trying stage 1+ to see how things go.
I have stock fmic at present. Living in the UK ambient temps are around 50F. If I trial this, does anyone think of issues I may well run into?
Any comments would be much appreciated.

I`m running 1+ on stock FMIC during winter and plan on going back to no + when it warms up (unless i decide to buy an FMIC).

Last session I had saw intake air temps peak at 50C/122F and i think it was about 3/4c out.

Be good if someone can say how high is two high for IATs as I log often and will then know when to change back

You may get away with 1 or 2 pulls at low ambient temps,

But stock intercooler will generally heatsoak, cause timing pulls and you will loose power as a result.

I would recommend you upgrade FMIC just like MHD recommend before going stage 1+

This!^^

You really can get nasty timing corrections with those stock intercoolers. My oem one would hear soak after 1 pull. Even stock I recommend people replace those crappy intercoolers, your engine will be happier

Check to see what kind of shape yours is in. Rocks and dents make them even less efficient.

Bimmer_Engineer · 01-20-2021, 04:26 PM

I don't think you're going to blow anything up...but a 5" FMIC is a really easy DIY. It took me a very leisurely afternoon including a run to Home Depot for a self-tapping screw. Flash to 1+, but get an FMIC soon too...

FWIW the difference between 1 and 1+ is quite noticeable...

Tyc0 · 01-20-2021, 07:42 PM

^ agreed, substantial difference in power

I can answer what MHD told me about IATs, i asked him in the past when i had no FMIC... he said you can run flash Stage 1+ without FMIC in cold months and the better is to monitor IAT with gauge to check you stay under 140°F.

snaeem155 · 01-21-2021, 04:36 AM

I mapped stage 1 and didn't find that it made a huge difference in power, however the jump to stage 1+ is noticeable.

Running the stock intercooler and I don't really do pulls at all, I just drive normally with the odd blip of the throttle here and there to get up to speed. IAT has remained fairly low/acceptable.

Possibly for me because I have an e93 the jump to 1 wasn't that great due to the added weight, but 1+ is perfect for my style of driving.

Perfect - thanks Studio - will change back when I start to see IATs hitting 60c

Willygbr66 · 01-21-2021, 06:23 AM

Many thanks to those that have contributed to the question. Like others I do not regularly do back to back pulls and in the area of which I live there is very few opportunities to do so without driving a little further from town. I did remap to stage 1+ yesterday and give it a trial and have to say there is a significant difference between that and stage 1 alone. I will continue to monitor my IAT's
(did not get above 60F)and ensure they do not rise above what someone has stated earlier. My plan is to get a FMIC however my priority to start with is to get a walnut blast done on the engine as at 110k miles its in need of one.

clegg · 01-21-2021, 04:19 PM

If you're not running the hell out of it, you will be fine. I have the stock FMIC and went to 1+. There is a very noticeable difference in power. It has been in the 30's F here though.

Hows the car running mate?

Did you fix the issues you had before?

Hey,

So the juddering at idle is still there - going in for a walnut blast at the indy I use this Wednesday.

The fluctuating voltage issue is gone since I went from a 70ah lead acid battery (was brand new) to a 95ah AGM.

Lastly the car does break traction now on stage 1+ but just feels like its struggling to breathe hence the walnut blast, its on 68k now and its never had it done.

It has however now developed a plastic rattle at idle from the engine bay which is annoying to trace.

Always fun with an N54.

Haha lol, N54's

At least your making progress,

Plugs and Coils been changed?

Chargepipe?

Plastic rattle, sounds like something is loose,

Have you done any 3rd gear Datalogs?

MHD states Stage1+ should be about 390bhp and 600nm at the crank, if I recall correctly, (with Intercooler upgrade)

snaeem155 · 01-25-2021, 04:15 AM

Yup plugs are OEM Bosch and coils Delphi's but I am on the stock chargepipe.

I haven't done any runs yet, I don't really need performance at that speed, I just accelerate (rarely) semi-aggressive to the speed limit and that's about it.

Had a 140mph crash as a passenger when I was 18 so I don't drive hard at all.

Upgrade to a metal one bro, stock one can crack/blow and leave you stranded.

140mph? That's asking for serious trouble,

3rd gear log won't take you to 140mph or anywhere near it. The reason it's recommended is because it usually shows any issues the car has under WOT. Obviously has to be done in a safe place, clear of traffic. You can log at upto 70mph at well, in a motorway.

It's more about drivability and acceleration, if the car is running well you'll enjoy it. You don't have to be ripping the nuts of it or going crazy fast risking your life to enjoy driving.

snaeem155 · 01-25-2021, 06:12 AM

I'll look into the chargepipe once I sort out the rattle and squeaking/creaking suspension.

fgpalmer71 · 01-25-2021, 07:35 AM

2 things....don't be shocked if the plugs don't handle stage 1+ well at all. I know lots of folks are running fine with them. When I flashed stage 1+ a 2 weeks ago I immediately got a cyl 6 misfire at high RPM. The car was on ~ 12k mile old Bosch plugs and coils replaced before I purchased it. I had NGK 1 step colder plugs on order along with the Delphi coils you have.....so I let the car sit until they came. I never tested to see if it was the plugs or the coils....it could've been the coils. Just replaced it all once they showed up. Plugs looked fantastic, again it could've been the coils. Just a heads up.

Edit:
Forgot #2....the rattle. For whatever reason once I flashed stage 1+ I immediately noticed a strange, never before heard rattle. I traced it to the alternator....I ordered a new voltage regulator at the same time as the plugs and coils....just as preventative maintenance. I didn't get around to installing it as planned this weekend. We'll see if that stops the alternator noise. Fingers crossed I can catch this before the alternator craps out....if that's indeed the cause. Might give your alternator a listen to see if that's the cause of your new noise too.

Update: Took the plunge at bought an MTC fmic. Price was £130 and it’s only had 300 miles on it so looks like a bargain. Just needs installing now for piece of mind.

I don't know that intercooler in particular, but I think that's a good investment. The install of most aftermarket ICs seems to be pretty simple and now you won't need to be concerned about timing pulls or performance on 1+. The difference between 1 and 1+ was really surprising to me...I don't think I'd want to go back to stage 1...

Willygbr66 · 01-26-2021, 09:51 AM

FMIC all installed today however weather not been great here so unable to take the car out for a proper run. Just out of interest I am using version 7 stage 1+ 95ron and fill up with Shell V Power (99ron). Any point in updating to the 98ron tune or even try the version 9 beta’s?
