Dinan Stage 3 Software & High Flow Throttle Body

BMW-x5-48is · #1 04-15-2015, 04:15 PM

Hey guys,

Got a quick question.. I am thinking of getting DINAN Stage 3 software installed on the car along with the DINAN high flow Throttle Body...

Do any of you have S3 from Dinan on the 4.8is ? along with the DINAN Throttle Body ?? and cold air intake?? Since Dinan does not make the cold air intake anymore for the E53 I bought the cold air intake from AFE - and want to buy the Throttle Body and S3 software from DINAN... Cost is close to 2 Grand for the whole package....

I cant seem to read anything on the Stage 3 update what it does exactly, except what my mechanic told me, that the stage 3 software aligns the vehicle's fuel maps to match the high flow throttle body. Otherwise the vehicle will lean out and the fuel mixture will be in correct, and that I should see more responsiveness and an increase in horsepower and torque.... Now the car has 80,000 miles on it... So just need some feedback do you guys think the Dinan S3 + Dinan throttle body are worth it?? or will it cause excessive use & wear on the car without much a increase in performance???

If anyone has stage 3 from Dinan & the high flow throttle body with a cold air intake any feedback would be greatly appreciated.... Is it worth it???

4.8is - cant find any superchargers for it... 4.6 now is a whole other story

From what I have read is that the Stage 1 is the remaps. Stage 3 is strictly for the mapping of the throttle body. There were some horror stories of people buying the Dinan throttle body and having a different tune (not Dinan) and it messing with the maps. It surprises me that a throttle body would make that much of a difference.

Also when I was looking for info a while back, it does not seem like there is really any real horsepower gain out of it. Most of the threads I read were from 3 series and they were saying 1-2hp. I know its a different engine entirely, but I don't think it will be much more. I'm sure there are threads out there for the N62 whether it be here or on the interwebs... when I was looking up on it I was looking on the M54.

To tell you the truth I was driving today in morning & car is working flawlessly.. Gear shifts smooth and all.. it pulls nice and strong.. its at 80k and being a 2006 it has a few years behind it... So I just dont want to be that guy that spends $2k for a tune and it messes the car up or does not do anything worth while... so just wondering if the throttle body for almost a grand and the $700 tune are worth it...

I have the Dinan cold air box, MAF, throttle body, exhaust, transmission and engine software. It was installed shortly after I bought my 4.6 new. I have over 114,000 miles on the package and it has performed flawlessly. HP increased from 340 to 369. Torque increased from 371 to 382. It made a big difference.

The range of air/fuel adjustment on your engine will provide for any increase demand from an air box and throttle body. For the throttle body to provide maximum benefit the air flow to the throttle body should be increased, an air box is likely enough for your application. In addition, the back pressure should be decreased, it helps even without any other mods. Finally, you would need engine software to take full advantage of the potential. I suggest you call Dinan and see if they can give you how best to maximize the throttle body benefit.

The best value is to add nitrous and meth injection. About two years ago I added Snow Performance meth kit and 150 shot of nitrous. Much bigger benefit than supercharging and far far less cost.

thank you for your input. I spoke with a rep today from Dinan he reassured me no negative impact will be made on the car with the tune long term if anything it will be a good thing for the car - as it will optimize the car for the increased air flow with the high flow throttle body + afe air intake. In addition the tune will add approx 220 rpm more to each shift point. Which is not a lot, for a used car, its a good thing. I also have removed the resinator, and have the supersprint catback exhaust system, which I believe should all work together in tangent & better better with the tune. I guess at the end of it all, you only live once, I think ima give the Stage 3 tune a try and get it done with the throttle body.. make the beast even more beastly...

It would be interesting if you did a before and after dyno pulls. Regardless, would love to here about the results.

I have Dinan badged 4.6is and also the 4.8is. I was thinking of doing the Dinan on my 4.8is but after much research and cost vs. benefit analysis, decided not to do it. The Dinan rep agreed with me that there are only marginal gains.

If you do it, I would also like to know before vs. after results, as bcredliner mentioned.

Alright well its done... I gotta say, there are positives to it, and negatives i guess.. to each is own.. I gotta get used to it now, as car is def a bit different..

First of all, the car is QUIETER when started and in idle.. how the fk?? with a bigger air intake (high flow throttle body) I though it i will make air flow more freely & make louder exhaust sound.. but its QUIETER.. hmm?? wtf?? I installed a AFE stage 2 air intake and deleted resinator, and added supersprint mufflers, and when in idle the car sounded like a beast in the rear even in idle the sound was hardcore... now after the HIGH FLOW throttle body & stage 3 tune - the car idles very quietly.. weird... very weird..

but under load - well its a different best... It def pulls better... hellla better.. where before it gave off more sound and less power, now it seems it has more power, less sound but i am puzzled as to why the idle sound is much lower, and the drone sound (which i kinda liked) when cursing around 1000-2000 RPM is also gone.. Upon acceleration of 3000 RPM and up the mufflers finally start to sing and give off that hammer sound right around 3,000+ RPM which was not as loud before..

So after 2-3 days of driving here is what I have:

1) Faster off the line.. The car when you floor it really gets going.. today I pressed pedal took off like a jet..

2.) Engine breaking has improved - coming to a stop feels better like the car is lighter, seems easier to stop. The tune must have increased engine breaking or changed up something related to it.

3.) Engine noise reduced on idle - after installation of AIR INTAKE from AFE and removing resinator and adding superspring mufflers, the car sounded very angry when in idle.. you could walk to back of car and just hear the car thumping away.. After tune and High flow throttle body, car now idles more smoothly quieter it seems... I am kinda dissapointed by that.. but at same time feel as the car/engine is breathing better/smoother/quieter.. Maybe adding the AFE Intake and FreeFlow mufflers without the right tune, made the engine software out of line, but DINAN tune adjusted engine to breathe better, so maybe its breathing easier.. Dont know.. cant explain why its so much quieter in idle..

below is a list of pro's / cons - after 3 day test:

PROS:
1.) Increased HP
2.) Increased responsiveness of car (reacts more quickly)
3.) Increased engine breaking (car stops better)
4.) Raised REV points
CONS:
1.) Reduced exhaust sound on idle

Again its been 2-3 days, so maybe car will adopt better over the next few days or when I get pass 100 mile break in period, but overall the car must be in the 400HP range now... must be.. def feels like it.

MODS Installed:

AFE Stage 2 air Intake (Claims 10-HP gains)
SuperSprint Free-flow Mufflers (approx: 8HP)
Resinator Remove (approx: 5HP)
DINAN High flow throttle Body (Claims 8-HP Gains)
DINAN stage 3 software (Fuel maps/etc). (should yeld 20 HP)

Car stock is 355 HP, iam sure the above mods gave it an extra 45-50 HP..
