Just wanted to make sure you all saw this new tuning option from Dinan. Looks pretty easy to install and I imagine it offers similar levels of power as a JB4. I currently have a JB+ on my car which I really like but considering giving this a shot since it's easy to install and I'm thinking should add even more power than the JB+. Thoughts?

I wish I had the balls to give it a shot.. Lol.

Looks like pretty significant gains, as usual.

I would get the DinanTronics X one just because you get Dinan points from it

Lmao, if the motor goes, so do my savings + who knows how long it would take to get a new one with the supply chain issues!

Limited info on it given how new it is but from the photos it appears to only have 2 connectors which will likely be MAP and TMAP connectors. I'm sure the Dinan is a good bit of kit. EDIT: it actually has 3 connectors, the third being to the Camshaft (angle sensors?).

By comparison, the JB4 uses MAP and TMAP connections, in addition to an EWG connection meaning it has an additional level of control and refinement, particularly for high boost level control. The JB4 also has ODB connection for additional parameter monitoring and tuning input. It appears they both offer Bluetooth control and connectivity, but the JB4 has more maps, especially for larger HP applications such as for people running Meth, etc. Other data like sample and intercept rates are unknown (for both devices).

But it will be interesting to see the reviews on the new Dinan controller, given it's approach of also utilising Camshaft data, I assume to adjust the timing in addition to MAP and TMAP - a slightly different approach to the JB4. If it's adjusting timing it could be a very cool option.

It's good to see more options hit the market from quality producers like Dinan.

Interesting that it reads the stock hp as 411 hp and 418 ft-lb of torque out of the box. That sounds about right actually.

The JB4 has these isame two connections, in addition to an EWG connection meaning it has an additional level of control and refinement, particularly for high boost level control. The JB4 also has ODB connection for additional parameter monitoring and tuning input.

Not to mention the JB4 also has years of tuning experience and thousands of installations behind it. It's hard to beat.

Until a few more details are released regarding the Dinan and a few others test it I'll be sticking to the JB4.

Just to clarify -- X actually uses 3 connections (MAP/TMAP/Camshaft), not 2 -- the generic base cropped thumbnail image for all the DINANTRONICS X's only shows 2 sets of plugs visible but supplemental imagery on those product pages shows the entire harness, etc. Nearly all the late model cars use 3 plugs but often older cars utilize only 2.

Thanks for the additional info guys. I've edited my original post accordingly. Would be great to get some more technical detail around the X Tuner. Are you adjusting Cam timing (intake/exhaust) with the 3rd connection?

[mblaucoupe135]

Thanks for all the thoughts so far! I'm thinking about giving it a shot since I figure if I don't like it, i can just sell it to someone on here and put the jb+ back on.

It's 100% safe—hundreds of thousands of tuned cars

If there’s no flash tune available by the fall, I’ll probably do this one.

I think I prefer this to JB4. This is my daily driver and I just want to set it and forget it. The JB4 seems to be for tinkerers that want to try many different mods, different fuels, and data log. Already seen so many comments about this map wasn’t doing what it’s supposed to so I tried this other map or I just took it off the car completely.

I think the vast majority of the tunes are fine but I remember when I has my 335i and people were doing the JB4 and plenty other flashes or piggy back deals. We had HP fuel pump concerns and other problems back then. Now that engine was the N55 engine was pretty solid back then but I went with the Dinan tunes after the upgraded IC, Oil Cooler and exhaust after it was all said and done. The hi flow cats were a nice add when I finally got around to that part.

I think the issue is having a car with a full warranty and jumping right into this stuff can be intimidating with the problems that people have seen from time to time.

Tuning is not for everyone for sure and comes with its risks and benefits just like everything else.

But the B58 engine has been out for years and it's been a very reliable one for tuners with proven brands like Jb4, Dinan, Race Chip,etc...

"DINANTRONICS X does not carry the factory matching warranty that Dinan is known for. DINANTRONICS X's warranty is a 1-year, product only warranty, that does not cover consequential damages or labor reimbursement."

What a bummer.

100% safe you say?

You willing to back that up with a new engine for me?

For Dinan and engine tuning we made the decision a year or 2 back that the factory matching warranty would be limited to the Dinan+ ECU flashes where more robust direct control could be achieved. If you want an inline with warranty there are a few alternative options out there but you are looking at 2x+ the price as well.

If I made my tune, I would have matched BMW's warranty. Some tuning companies offer a warranty, and they have been in business for tens of years, they must not be replacing engines often, or they'd be bankrupt.

If you run a map too aggressive for your mods or fuel, you can damage your engine. Outside of that, it's very close to 0%

If you are not comfortable with odds you are getting with a simple tune, it's understandable as tuning is not for everyone. But Im pretty sure the odds of getting into a car accident are higher than damaging your engine from a tune.

If Dinan offers a tuning solution that has the warranty matching, post a link and I'll order it immediately for my M240i that will be built very shortly lol.

They only offer warranty match on their ecu tunes which they don’t offer for our car.

[Ricochet48]

The Dinan option looks promising (especially appreciate the 3rd parameter). I wish they would post the dynos from the other mappings. The one provided is the most aggressive (#7), while it ships in the more reasonable #5 mode that most would run. Also, what are the differences (e.g. boost psi).

JB4 is still a decent option, but only has 2 parameters.

Carbahn seems to be the only one with a matching warranty option (for an additional $750). Their 93 dyno is likely very close to what the Dinan one would probably be in #5 mode or so.

Wish the DME was unlocked for flash tunes as those are generally the best options (and as Dinan noted they would offer warranty matches with those).

Haha, I get it. I just liked the 100% figure you threw out there.

The kicker is "too aggressive for your mods or fuel". In my experience with flash tunes or piggybacks, even using the least aggressive mapping has always caused pinging, which makes me quickly revert back to stock. It's happened on a few cars of mine over the years, so it could be something related to the local fuel quality, who knows.

Just my personal experience! I am jealous it works out for most people, but I don't wanna risk my bran new BMW warranty for it.
