How to: MSD81 Upgrade on a Budget!

[@milehighboost5521]

Index 5 and 7 injectors still sort of working?! Wow! I had a whole set of index 11 and just found 3 had bad leaks so i ordered some index 12s. Huge difference and wish i had figured it out sooner. Had issues starting for a while but great tip about where to upgrade to an dme81 in case i want to do that in the future.

[@ilyld2003]

Amazing how much the electronic gremlins almost outnumber the mechanical issues!! Great video as always! Looking forward to the injector and spark plug project.

[@Nico_335i_DCT]

Very nice Chris. When you do have 2 sorts of injectors, you have to make sure every bank has the same index injectors. So for example bank 1 only index 5, and on bank 2 only index 7. Very important rule. And don't forget to change the injector seal and couplers., when moving the injectors to and another cylinder. Good luck. Dutch regards, Nico.

awsome videos, much to learn, thank you from Herzegovina keep it going !!

[@TheBimmerBarn]

Thanks for watching, Xer! 😎

[@nicholaspoyle938]

can i switch a msd81 with cas and key to car as a whole plug n play or will that not work

[@TheBimmerBarn]

IF the engine/transmission configuration is the same, it should start the car and let you drive it, but you will get errors on the dashboard from the "coding" not matching.

[@simonshek8701]

Keep the cover and cabin filter off yes. Its perfect when u find perfectly water falls perfectly into cylinder 6. So it wont matter what u do. Evertime plug will be wet. So use the plastic coz even washing the car and game over lol and gently blow the water out and cover the shit up

[@simonshek8701]

Sorry i know coz my driveway angle proves

[@ArtemWeekly]

generally speaking with DME fault codes would you recommend resolving the computer issues first prior to attempting to make any changes mechanically?

[@TheBimmerBarn]

A dme is expensive, I'd recommend checking out the car mechanically before replacing a module. You cna always move injectors around to make sure that it's not just a bad injector in the first place. Hope that makes sense!

[@robertog813]

Hey enjoy your videos I just got my FIRST 08’ BMW 535xi having issues with my ECU DME module I guess they ‘swapped’ the computer before registering it Has a different VIN on it Can I program it without having the original one ?

[@TheBimmerBarn]

You should contact my friend Remote Bimmer Coding (on Facebook), if anyone knows the answer to that question it's him!

[@kelvinxu5638]

How about e82 135. Can upgrade too? Misfire cylinder 4 also. After changed New plugs and new coil new injector still misfire

[@Hashbrown2169]

Change ur mosfets or look for damage in the wiring harness

[@ThaHammieJaassee]

question i just did a new head and head gasket on my engine i put it back in my car, now the car wont start it turns over when i engage the starter but it just spins the engine it doesnt seem to want to start. i connected mhd wire adapter to the obd2 port and it says mhd could not communicate with dme. do you think a bad ground will cause it to crank but not start and have no communication with the dme? do you think my dme bricked itself and i have to get a new one? :o

[@TheBimmerBarn]

I would try a normal diagnostic scanner, not just your mhd app, and see if the DME communicates, or has codes. If the rest of the car modules communicate but not the DME, you have a problem. Otherwise, sounds like it could just be something you forgot to connect when you put it back together! Good luck!

[@scarface16134]

Let me ask this..... does the vin match in MHD? If it doesn't hot me up and I can help.

[@TheBimmerBarn]

I think it does, but I haven't gotten to the point yet. Will let you know!

[@dinonuggetcooking3109]

Bro can you help me with my 335is I replace ecu, keys , central control electronics ,and the cluster now the car is not working

[@TheBimmerBarn]

You can probably get the car started with the new cas,key,dme, but in order for the car to "accept" the new modules, you need to code the car and make sure the VIN matches all the modules. Something you can hire someone to do for you. Could be related to your instrument cluster issue.

[@N54.S6]

Can i use an MSD81 on my 07 E90 335i?

[@TheBimmerBarn]

Yes, and you should do the upgrade! Also, if you have an 07, look into retrofitting the oil cooler from 2008 models and forward, it helps the motor run cooler!

[@N54.S6]

@@TheBimmerBarn ya I got this duel oil cooler running! It made a giant difference, even more so considering the tune! Thanks

[@abdulazizss5281]

[@OsamaBinLlama]

Could I upgrade to an msd81 from msv70 on an 07 525i e60?

[@TheBimmerBarn]

No, the programming and board is too different. You'd need another MSV70 if yours failed
