Sorry bud not much help there

Ok so I will have to wait until Sept 2018 for a remap. I'm am sure by then, some companies will have perfected them by then.

[Smee]

In all honesty if you have 1 I wouldn't swap.

Tbh companies have perfected the remap dms, more-bhp to name 2. It's an ecu out job no matter what unfortunately. No way to do it via obd

There is one company who claim to be able to remap via obd. BW Chiptune.

just read that post. one of his dealers I guess you call it. Someone who uses his cable is local to me and he does ecu out so maybe not all fxx cars?

For those interested, I'm taking my car on the rollers next Thursday. Had hoped to get it done this weekend, but they need a few hours to do it properly.

Going to do 3 runs: Stock, C7 & E7. I currently have mine set to E7 so would like to see what it's putting out, but also how the power and torque curves compare to map C.

Will update this thread with printouts once complete!

Had it on for 20k now with no real issues but ive only tried C6,D6,D5,C5 and now C4.
All have give me that dreaded cut in power at around 100mph when flooring itin sport plus and gearstick to left. It seems to happen right at high revs and feels like it hits a limiter. Foot off the gas and its back to normal. Its so severe that I reckon if I was playing and it happened whilst a car was behind they could run up the back of me.

Change to MAP E - seriously
I ran mine between C4-C6 and had fuel cut under heavy load situations, I never thought that changing to a more aggressive map would cure it, but sure as shit it did. The cars now running on E7 and is happy as a pig in the proverbial, with the added bonus of even more POweeeeeerrr

Happy days

As we have the same engine I am looking forward to seeing the results, I have settled on D8 so just in the middle of your two maps

Hi guys I am looking to buy a CR2 box once my ACS Springs are fitted. I want the CR2 as it keeps it below 700NM (gearbox limit?)

Has anyone done 0-60mph and 0-100mph with these boxes

To be honest, with most of these boxes, you prob wont actually get to the claimed top end these manufacturers quote. Its all a bit of marketing. If you look at Smees first post on this thread with the chart from a previous dyno day, the maximum seen on the rig was 525 lb/ft (711Nm) at the flywheel and 410 lb/ft at the wheels (555Nm). That was the Steinbauer box.

You are quite correct re the ZF 8HP70X box having a manufacturers limit of 700Nm. (8HP70 on the graph)



I think with pretty much all boxes, the chances of them being anywhere near 700Nm is low and the amount of times you'd be exploring that top end of the spectrum would be minimal (not to mention a bit of fat on the bones ZF will have on the 8HP too; Input Tq capacity 760Nm). In all the research I did (with huge thanks to Smee), I never once came across anyone who had broken their gearbox after fitting a tuning box.

As for 0-60 times. About two weeks after I fitted my BS Pro+ Boost box, I did a launch and (not terribly scientifically) saw about 4.3. Prior to fitting the box using the same road in the same conditions, I'd seen about 4.6 (pretty much bang on BMWs figure). Feels a darn sight more rapid off the line.

Has anyone been able to code the new MPPK style recalibrated Sports gauges to read above the standard 640Nm?

[335dxdrive]

Cheers so realisticly I can expect around a 20 bhp raise

Would it take a second off the 0-100 mph time or am I dreaming?

don't on own for sure but a second off to 100.ph sounds reasonable.

with a box 35 to 45 is what I expect. when I get on the rolling road in may I'll know for sure hoping for 360 700nm but I am on the highest setting so if bluespark are correct 370 bhp 721 nm. we will see

[JLR1969]

I would be pleased to get to 300BHP and 620NM this would be a good increase over standard but not stupidly extreme

We will see in May

How did you get on with the rolling road?

Holding off posting a full review until I get the graphs emailed across, but quick summary as follows:

Stock the car ran 258.6bhp / 409lbft - so pretty much bang on what BMW quotes.

In the default mode (C6) the car ran 286.1bhp / 486lbft and the dyno plot pretty much mirrored the stock curve, which is in line with guidance from Bluespark.

In the max setting (E9) the car actually produced less power (282bhp) but more torque (500lbft). This came in much earlier however, but then tailed off compared to map C. Again pretty much what Bluespark have advised.

Easier to explain when I have all the graphs which can be seen. I also ran C9 and D7 so full report to follow.

Pleased with the results, albeit down on the ultimate power figures Bluespark quote but torque surprisingly higher.

Interesting result, I run D8 so I guess it's where the torque lies. I would have hoped for more power but I guess it's just a number as the car does feel a lot better than standard be interesting to see what my car makes in May

So +10.8% BHP and +19% Torque which I would be pretty happy with as torque makes a lot more impact for me.

Hitting the 300BHP is my target but that's vanity

[Smee]

same as you. was chatting to Kev yesterday when he was running the car and was surprised by the power. (might be worth a question to Edd??) but torque (which is more what i care about) is actually up which does make me happy. spend more time down that end of the rev range than the top end anyway.

Stock = 554nm
bluespark claim = 650nm
result c6 = 659nm
result e9 = 682nm

I've left mine in D7 which was the setting I was happiest with overall, and one I did like when I initially fitted the box.

C9 actually made 291bhp for me (forget what the torque was just now) but when it was on the dyno the technician could fell the car holding back, which as reflected in a dip in the power curve around 3500rpm - I assume this is the fuel pump limitation that's been discussed previously. Either way the car did not like this setting!

[Stoo]

I thought the 35d was 620NM stock anyway?

[Smee]

Kev has 330d

[KCH1984]

It's confusing - some of us are running 35d and others 30d.

Those numbers are for my 30d.

[Smee]

Tbh once you do your review I'll steal it and add it to the main post and any other useful information.

Interesting the graph I listed above for tdi tuning box made good power but torque well down

[Stoo]

Ah, I thought as much.
I got confused Lee, thought you were talking about 35d figures as you have a 35d
