Why I had my BMW 435d Stage 2 remapped by Unicorn Motor Developments. Much better than DMS maps. 

Yeah, you wouldn't miss Charlies car !!! Bumble Bee :)

Let me know how you get on 👍

What was the result of the remap?

396bhp and 810nm torque. The bhp is probably higher but the air filter was clogged and when I got home ordered a K&N one. Plus it was hitting the torque limiter in 6th gear on the top of the runs abs changing up. Since then I’ve added the XHP gearbox flash and that has removed the limits and feels much better. I reckon bhp is about 410 real life.

@@richardtorr-T7 This will definitely void the warranty right? Are there any ways of getting more power and torque out of the 435d without voiding the warranty?

@@Arman-nl6mg any amendments will void the warranty but if that car is out of warranty anyway it doesn’t matter.

@@richardtorr-T7 I wouldn't use k&N, whilst it lets more air in, it's not very clean. The oil can also mess up the MAF sensor.

Engines Rule the car has performed faultless over the last 7 months 👍👌

Also, the gearbox usually restricts torque (BMW do anyway and ZF actually says it can be higher). I applied the XHP gearbox flash and that definitely made a difference and was as noticeable as the original map. Definitely need to do both together.

Cobra do a dual exhaust set up as well, just checkout their website and take it to unicorn for a fitting and remap

imyk 611 thanks for the feedback. Yes, I’m getting about the same performance again and you can definitely feel it. It’s much better and I do regret the DMS map (down to cost), but the positive is that I wouldn’t have found Unicorn without being not as impressed as I was expecting. I had an e92 335d previously and that had about 340bhp and felt quicker. The chap that did that one is no longer mapping. I’m really happy with the performance and nothing negative to report.

I’ve had no issues with that but it’s up to each owner. I’d definitely not go over the recommended intervals.

Hi Alex, did you have it done at Unicorn? I drive motorways and A roads and if driving normally get the top 45 ish mpg. The average since I’ve had it is 39.7. Some maps may just be overfueling. Also if that’s the case or sensors are being tricked it may be reporting wrong, so try the old school way of full to full and noting the distance and how much to fill it up again.

mikey335d I’m a little frustrated with DMS as I now know that disabling 4wd means more rolling resistance and therefore will overstate the actual BHP!!! When I took it to Unicorn and they didn’t disable the 4wd then it showed 354 bhp. After Unicorn mapped it on the same day with the same dyno it was showing 386 bhp. It feels even better so is definitely an improvement. I just wish I’d have gone to Unicorn first and saved some dosh ☹️

@@richardtorr-T7 uve got me curious now about mine! 🤔 so ur saying the car is alot faster with the unicorn map compared to the DMS map?? Did u have all the mods dun to the car when dms remapped it??? ie intercooler or did u have these installed afterwards, and had then installed before u had it remapped by unicorn??

mikey335d I had the intercooler fitted a few weeks before going to Unicorn, but although he could eek out a few more bhp because of that, he’s got 40bhp more!!!! When driving away from Unicorn I could feel the difference. I’m going back on 27th October as Rick has got some more tweaks with the turbos and has offered to apply it to mine; which will trigger another video 👍

@@richardtorr-T7 I may have to go visit rick, what Kinda torque were u getting before and after the unicorn map? I've noticed u have had a alpina gear box map? What has this dun I've herd about this

mikey335d can’t remember the original torque offhand but it’s 800nm now. Alpina Gearbox just is better suited to a mapped car as Alpina cars have similar performance. Also shows to current gear on the instrument cluster and when in sport mode uses 8th gear. Plus stays in gear longer when using the paddles. Rick charges £125 for the gearbox map so I’d definitely have it.

No, dpf is still intact.

K A it is a go pro (hero 4 silver) but without the waterproof case on 😊👍

how is it mounted without a case? Thanks for reply

K A it is in a black frame with a standard connector at the bottom rather than the waterproof case.

None dare race me 🤪

Would be quicker id imagine certainly to 60 anyway

I’m a car mechanic myself, and I have a 435d xdrive coupe with 402bhp and 750nm, it goes from 0-100 in 3.9 seconds with summer tires on good road conditions. I can proudly confirm that it easily takes an m3 and m4 in a drag race due to the xdrive

Oscar Sebbelov fuel consumption?

Bartunc Akbaba depends on traffic and which mode I’m in, when I’m cruising normally in eco pro around 17km/l in the city, but on the highway in eco when I’m driving an average of 110km/h 18-22km/l, my record on one liter is 27km with an average speed of 90km/h

Easy to install, but you need to raise the car up, so took it to a local garage and charged me an hours labour.

Intercooler was about £700

Hi Lucijan, there are two zf gearboxes and I think mine is rated at 750nm. However, the torque only goes above that level for a few seconds and I don’t launch control it. It’s been fine for over 15,000 miles 👍

@@richardtorr-T7 oh thx for replying

these cars have the zf HP70 gearbox, 700nm max, if you want to go over that then you would need to upgrade to the HP90 if possible, btw there are NO 750nm variants used on 3/435 xd's although I believe other manufacturers do use them

stubones I’m having some building work done at home and that’s taken up my time. I’ll be digging out my GoPro and have some more videos soon. I’ve had the Mperformance carbon fibre body kit fitted, so that will be the first one.

Not worth mapping 320's unless its the 163 hp version

I only got a very small amount at about 4500 rpm (but Charlie didn't at all). Charlies uses BP Ultimate and I've started using that and it's absolutely smoke free.

What fuel were you using when it was smoking? Bcz i inly use shell, either normal shell or v-power

it was Shell v-power. I now use BP Ultimate and find it much better.

Do you mean Unicorn or DMS? Unicorn are great and had over 4 years and 50,000 miles on the map with zero issues.

Yes, thats right. Plus I have the Alpina gearbox map, but that doesnt make a difference to the BHP.

Yep - that's all (K&N air filter, but that doesn't make any difference).

Richard Torr where do you get the alpina gear box map

@@JMass3011 unicorn do it

Paul Sheard I’d definitely go to Unicorn (mention me!!). If you have any doubts, speak to Rick and you’ll know in minutes that he knows his stuff and is not prepared to push the car too much, so it will still be safe and not smoke 💨. Mine has now done about 25k miles on the map and no issues at all. The exhaust or the air filter will make virtually no difference but for me the filter is cleaned more regularly and is more cost effective. The exhaust is just aesthetic. I can’t have the exhaust as I have a BMW retractable towbar (see my other videos which are gliding and I tow my own glider). You’ll notice a massive difference. The only regret I had was not doing it sooner !!! I’d get the Alpina Gearbox map done as well. Rick does that at the same time.

Paul Sheard the Facebook group is F3x owners 👍

@@richardtorr-T7 Man thanks for taking the time to reply. I'll certainly give Unicorn a call and mention your name :) . atb

@@richardtorr-T7 Great I'll sign up, thx again

Paul Sheard they are closed on Mondays as they are open Tuesday to Saturday each week.

Hi Andrew, no problems at all. Rick @ Unicorn says that it is only over 700nm (I thought the later versions we rated for 750nm, but could be wrong) for a small period and is over-engineered anyway. Just make sure you only drive it hard when the engine is up to temperature to ensure everything is warm and lubricated !!! Mention me to Rick and you'll get the red carpet service as I'm a regular there and he applies frequent updates for me. Get the Alpina Gearbox flash done at the same time, if you haven't already it makes a big difference when done at the same time as a remap.

@@richardtorr-T7 thanks Richard I will definitely do that as was also considering the gearbox map as have heard they are much better post map. How much is the gearbox map out of curiousity

andrew O'Rourke £125 for the Alpina Gearbox map 👍

@@richardtorr-T7 definitely worth doing then for that price. Thanks for your help

Richard Torr who did your Alpina gearbox map?

Leigh Barry no mate. Just the intercooler.

THEG12EG it’s pretty quick. Get the revs at 3-3.5k and the top end acceleration is nice.

Mine pulls very hard after new map and ic. Pulls strong right to redline if need be.

Whats a back box delete mate. And what work you doing to your car. And where from?

Let me know how you get on (either here or on the F3x group). Charlie's figures are about 20 BHP lower than his original map, but that's down to ambient temp and new tyres etc. Its close enough to 400 BHP and it drives very nice and that's all that matters !!

yeeah spoke to charlie lots, saw his figures down in 380s, its gonna be hot day on sat when i get my rr done, but will let you know, im hoping higher than my 393bhp before intercooler and new map.

Lee Kindell what was your figures in the end? What’s the mods; remap and wagner?

K A oh hi. Well Surrey rolling road last week. 409bhp and 575ft lb great result and on a hot hot day 25 degrees

esuohdica it costs £500 for a remap, but speak to Rick or Chloe and mention my name and you’ll get the red carpet treatment !!! I’d also recommend the Alpina Gearbox map for an extra £125 at the same time 👍

Cheers for the reply, I'm really tempted with the 435d GC or 335d Touring actually. Thanks

esuohdica my friend is having his 2018 445d GC done on 27th October at Unicorn and I’m going with him to film it, so subscribe if you haven’t already and you’ll get the notification when I upload it and other videos 👍
