Dinan Dinantronics Sport Performance Tuner For BMW B58 Engines

[RyanA90]

People on this forum has used the JB+ (not JB4) which is basically a boost controller and has seen good results.

I wanted to try something different and more user friendly. If this doesn’t give good results at the Dyno session I’ll try out JB+

My comment wasn't directed at your choice it was in response to @PikkaGTR question whether a boost controller will do anything.

"Not over powering but a decent boost"
Sounds a bit vague for something I'm putting on an expensive engine.

Just installed this and have seen peak boost anywhere from 24-26 PSI. No CEL.

I have a dyno session on 3/10, we'll see how this thing performs!

For background info here are my mods:

Fuel: 91
Intake: CTS
Downpipe: Kenji 200 Cell
Exhaust: OEM
Wheels/Tires: OEM
Clutch: OEM no problems
Mileage: ~2k

Are you still using this?

No. The app was buggy. I have the JB+ currently. Set it and forget it type thing.

I have JB+ but threw a check engine light while doing some triple digit pulls in 90+ heat on the maximum setting. I cleared the code but backed it down to 70% after that. I have been curious about the Dinan

What fuel are you using? I have no problems with it using e30.

93 I have never used E85 at any ratio. Setting 4 was fine for 1k miles until that hot day and it threw a “manifold excess pressure” /limp mode at me. Didn’t clear either and I had to use BimmerLink to clear it.

Ethanol is hard on a system that isn’t 100% designed for it. The seals and injectors would worry me

Was that the only reason you switched to JB+? I have a JB+ currently set at 3pm dial with 91 oct fuel. But it’s weird, I don’t have very smooth shifts at all, overall less aggressive downshifts and less pops/burbles from the exhaust. I wanted to switch to this for a while before I end up doing a FEMTO Unlock later next year.

You should mix about 2 gallons of E to get the full benefit of the JB+. It was smooth when I had it before I upgraded to JB4 and got a custom map 6 tune.

yea I got recommended that, the thing is though the e85 pumps kind of out of my way, so I don’t think I can keep up with going to it unfortunately :/ Did you have an overall smooth experience with the Dinan? I’m worried I’ll run into the same issue as the JB+ lol.

Gotcha. Quick question, was the install the same as the JB+? If I’m able to pick one up used for a decent price I might pull the trigger on it just to try it out. Appreciate ya getting back to me btw!

If I remember correctly it’s really similar. Not difficult at all.
