Easiest Way to Measure Boost?
I need something I can measure boost with, just periodically...I don’t want to install a permanent gauge.
Is there something relatively cheap I can buy and plug into the odb-II port? Basically, I want to verify my Dinan stage 2 is making the 13.2 PSI boost it should. Last edited by BayMoWe335; 09-17-2020 at 10:57 PM.. |

You can get the MHD app and buy the monitoring app for like $50 I think it is. You'll need an DCAN cable and adapter for your phone or the bluetooth obd adapter

Only 13psi at stage 2? You should be using MHD for more than logging...

No doubt, but this tune has been installed for 10 years. All this stuff wasn’t around back in 2010, so I worked with what I had at the time. Dinan was the safest option to keep warranty. Now I just want to make sure it’s still there. I’d put any tune on at this point with no hesitation, but the Dinan is on it.

If you just want it to measure boost it periodically to check, don't install a permanent boost gauge, but instead, buy some feet of vacuum line and a T, enough to go from underhood at the intake manifold connection (where diverter valve are connected) to driver by the window and a basic boost gauge.. everything should be around 25$.

Do you have a smart phone? MHD is available for IOS and android now. Don't be a cheap ass. It's worth having the tools for this car. |

But if you just want a mechanical boost gauge, consider this one I put together for $10. It's calibrated for exactly 13.2 PSI

OK, I’m convinced. Can I just buy this and download the monitoring license on my iPhone and I’m set?

My 335i has coded LCI taillights. Will these flashes erase that info and bring back the bulb check errors? Or does it only touch engine mapping and light codes are separate?

Well if youre just getting the monitoring module it doesnt touch tuning or anything. It simply reads what the engine is doing.
Tuning only affects the engine it doesnt mess with what you have coded.

What if I eventually want to flash to MHD map 1+ or something? Would that not touch the taillight coding? I remember the taillights were coded using the FRM, but I’m not super familiar with this stuff obviously.

My car also has a Dinan stage 2 tune...does that mean I have to remove that first? If I flash back to stock, does that again just change to the stock mapping for engine and not touch my coded lights?

Yeah, flashing a tune will not mess with your coded lights. No worries there. And you wouldn't need to remove your old tune to flash a new one. It will simply overwrite it.

Are you looking for more power? MHD will offer you more power/performance but if youre happy with the dinan tune and performance out of the car there isnt a real reason to upgrade unless you either, like i said want more performance or want to take advantage of some of the newer features available through MHD

I've used MHD stage 2+ and didn't really have any complaints. I'm not currently using it because I wanted to be able to modify my tune and learn how to tinker with that kind of thing a bit. MHD tunes are locked, but so are most others. As far as how MHD Stage 1+ compares to Dinan Stage 2, I'm not sure. All I know is that Dinan is a dinosaur and MHD is actively being updated and has lots of features. If I were you, I wouldn't be afraid to try the MHD Stage 2 map pack. The FMIC is a whole lot more important of a requirement than downpipes.

With the WiFi adapter, do I need to plug into a trickle charger just in case? |
