[@JermaineLeeBlueprintAuto]

Keep making videos bro your doing an awesome job.

[@markt9438]

I don't know if anybody else notice but no one has done a DIY on a PCV valve for these cars Good job!

[@JaredMotola]

Sent a picked up MSD81 to replace my MSD80 To Renn.. Thanks for the quick turnaround! When you install into your vehicle don't forget to do a TPS adaption reset

[@MrNicoe36cabrio]

Wow. That guy did a great job. And that price is a steal!

[@nickolascain2994]

Nice content! Welcome to the MSD81 gang sir!

[@impacbmw1462]

There are also many other tools that are cheaper and can read and write isn 😎 But Autohex & BmwExplorer are best 👌

Definitely wanna see some content of your new turbos when their ready. And even a Dyno your car has come a long way on this channel

[@MarioDallaRiva]

Awesome! Super content. Kudos to Renn Motors.

[@machtschnell7452]

Thank you for confirming that the MSD81 has functional upgrades over the MSD80. I know that the dealers are pretty insistent about upgrading them a few years ago.

[@VehicularDIY]

They are awesome, zero issues. The power video is taking time cause I had to resolve the stumble issue.

[@XxTaStETheBeAsT]

Vehicular DIY thank you so much for replying i was waiting on your review for them to get a pair myself. Sorry if i came off like a dick just been wanting to know so long 😂.

[@VehicularDIY]

Hey np, yeah I don't think anyone would be disappointed with them for what they cost.

[@Angel-rn2lq]

Vehicular DIY maybe the fuel pressure regulator is leaking

[@nikhilsoni1773]

So you can still flash back MHD tunes after upgeading your DME? Also what are some benefits to upgrade your DME?

[@Jetsrockful]

Thank you so much!!

[@NUNYABIZNNAAAZZZ]

Can someone explain the purpose of this update? Better performance? Please advise. My E90 is stock, but many many new parts like Index 12 injectors etc

[@rennmotorsllc9787]

The MSD80 suffers from 2 common defects....1.Mosfets burn out, causing misfires and 2.Internal power supply fails causing different issues. So, BMW came out with a new updated DME..... the MSD81.

[@NUNYABIZNNAAAZZZ]

@@rennmotorsllc9787 Thanks. Ill get mine shipped out!

[@mikedemi192]

I have a 2010 e90 n54. Does my car have upgraded msd81 from factory?

[@SL9SH]

Mike Demi surely, MSD81 started from late 08 built date

[@scarface16134]

Mani really wish you would of went with ktag and bench flashed the DME could of learned a lot

[@e90lownslow14]

Do these guys flash 328i to 330i tune for 3 stage intake manifold? I tried flashing my dme and almost bricked it. Have to tow my car into a local shop to re program everything.

[@hackn3y199]

Did you have your firmware updated on the MSD80 before you swapped? Wondering if that might've caught the 02 sensor issue? I just got done updating all my modules, kombi was kind of a pain.

[@nicholasmehlert]

Help me understand this. You need to find or purchase an MS81 unit used then be able to have someone “code” it via Hex, etc. the MS80 cannot be upgraded, correct?

I did this but I’m wondering if I can pass smog with this upgrade. On mhd it show donor vin and my original cass. on impa it show my original vin. you think I’ll be good with ca smog?

[@dev8027]

I’m also in the Houston area and I was wondering when you say stumble you mean misfire? Because my car already had a msd81 and had a constant misfire after new coils and plugs . I swapped the ecu for the old msd80 and the car idled better. I the. check the codes and seen I needed a upstream 02

[@guillermoortega6802]

Any one help please. 2008 328i hardtop convertible cranks but won't start after replacing the battery the anti-theft activated and I followed the steps on the manual to disactiva it but still it cranks but won't start. Some people told me to replace crankshaft I did and nothing Someone else told me to replace camshaft I did and nothing this mechanic also told me to replace the alternator I did and still same thing it cranks but wont start

[@deivyleon409]

I’m having a single cyl 4 misfire only when accelerating it now has new spark plug new coils and new injector in that cylinder and still persists . my valve cover is leaking does anyone think that could be the cause lol could it be a o2 sensor ??

[@Othermind972]

hello, what the difference between MSD80 and MSD81? i can"t understand ppl who speaking english. i have ear condition.

[@brakthru2]

If I go with this service, is the secret code being taken from the cas3 and written to new dme or vice versa. I still have a functional msd80 with several custom tunes for my hybrids that wont work on the msd81 until my tuner has time to redo the maps. I believe he's back logged and my car would just be sitting. I need to know if my original dme still work with my cas3 if the cas3 is synced with new dme. As well as keys. I have ability to code, program, flash and write vin. Also, does the original vin stay on the cas3 so mhd can read it? And your just changing vin in new dme. Or does the cas3 have the original vin and new vin?

[@rennmotorsllc9787]

We can do it either way. If you still want to use your MSD80, then let us know and we will read the ISN from the CAS and write it to the MSD81. All coding should be correct to your car after we flash/code the MSD81.

[@lukegray6441]

Where did you purchase the new MS81 unit?

[@flexing1013]

Nice

[@Trusty335is]

I have an e92 2013 335is and when I checked the system with protool, it said I have MSD80. Wouldn’t I have MSD81?

[@angelpena8121]

You run into any problems yet?

[@Trusty335is]

@@angelpena8121 not at all but I have really low miles for the car. Got it at 32k miles and now has 39k miles.

[@briankeitharellano2314]

How much does he charge to program the dme... my code reader says DME : DIGITAL MOTOR ELECTRONICS FAULT 9.... can I just send my dme to him????

[@VehicularDIY]

I think a couple hundred, would be best to reach out to him to confirm. Yes you can send it along with your CAS.

[@rrudydedogg3779]

Some time ago I flashed the DME in my 2011 E92 335is with an MHD upgrade to Stage 2+ and I saved the original factory programming in my phone. If I changed my DME as you did would downloading the info from my phone be adequate?

[@rennmotorsllc9787]

Rrudy DeDogg No. it doesn’t work like that. What you see in the video is retrieval of the ISN from DME and then we write the ISN into the CAS. Installing a tune or factory flash program is a different thing. Also your car should have the MSD81 installed from factory.

[@machtschnell7452]

You have an MSD81 already. If it works, it is good.

[@shafieksalie3119]

Very nice video 😂😂😂👍

[@candycornpeeps]

Is it true that the LCI 335i have the MSD81?

[@VehicularDIY]

Yes all LCIs come with the msd81

[@adriangutierrez8177]

gelera18 328i has a completely different ECU. MSv80

[@ni3k777]

Did you need to buy a new MSD81 or reprogrammed a used MSD81? I need to buy a DME since my old one has a 30bb error

[@adriangutierrez8177]

Reprogram used MSD81. Found one on Ebay for $200 off of a 2009 335i with 67k miles. Took me a week, guys buy MSD81 in bulk at junkyards so I had no luck finding any.

[@oceankham]

you can always replace the MOSFETS in the ECU and should solve your issue.

I’m getting a 2c2e could it be my 02 sensors but my old dme or Ecu not picking it up?
