Just had my 1.4 diesel ECU re-mapped today. What a difference it makes, its like a bigger engine altogether. Loads of torque and acceleration is spot on.

My car ran 73bhp as standard and now is hitting 103bhp with no other mods (impressed).

The work was carried out buy a guy called Nick from REDITUNING based in Liverpool. He traveled to my house in Shropshire, downloaded my ECU, amended it, and put it back. That was it, nice and simple. Should not effect the TLC as well as the ECU still has the same check sum as the original.

I will post details of MPG at a later date after I have finished thrashing it so I can compare figures to what I have been use to.

If anyone requires graphs to show the difference email me and I will pass them on.

Now to find a cooper to race to put it to the test. :D

LOL-Great stuff :)

Welcome to MINI 2 :D

How do you know its precisely 103hp after the remap? Did he bring a rolling road with him?

I was thinking that aswell actually?

What Wheels is your MINI running on?

Thanks Interceptor looks like the mini forums are full of interesting info, only had the car a month so reading up alot

I was waiting for that one to about the rolling road :p

He used a multi axis acceleratometer (I think thats what its called), which basically is a box of tricks which is placed level on the floor of the car. The weight of the vehicle, full fuel tank and our weight is calculated then several test runs are done. This data I guess is used as a bench mark.

Find a level straight road, start in first and red line in second and stop.
My vehicle averaged 73bhp (non moded) which is about right I think.

The ECU is re-mapped and more test runs are done using the same calculations as before.

It's probably a bit more technical than that, as I know alot more info was calculated before we did the runs, but cant be far off for accuracy if mine was only 2bhp below book (stock)

The wheels are standard 15 inch alloys with run flats.

If anyone can tell me how I can compress some jpegs I will post the results here.

Ahhhh right.
Yeah 73 bhp is Probably about right-Thats what mine was. Now running at 105 aswell. Pleased with the +30 Result :)

See if this works :D

This is the results from two of the runs as std and re-mapped

Thats very good-Still awaiting my Printouts for when mine was done.
Did the guy print them out then and there?

This is the good bit, Nick at REDITUNING needed ECU info on a Mini D version with details of the BHP gain so he could give more details to new Mini D customers who wanted the conversion as per advert on ebay, I think he still has one for a Mini One petrol so grab it if you have one. Anyway mine was the first D version he has done (gulp). To be honest he knew exactly what he was doing and what could and should not be altered within the engines capabilities so I had no worries

Because of this he showed me all the test results as he was going through them and what modifications to the ECU had been made. We went through all the figures as he did them and emailed the graphs as I asked for them for my own interest this evening.

To top it off my total cost was 50 quid as no one else bid.......................Yeeehhhaaaaa

Wow thats a Bargain-Mine was 10 times more than that!!! :eek:

Did it pay for him to Travel from Liverpool to Shropshire, do all that work and only 50 quid??.......

I'm still smiling now as I've read in the forums costs are between 350-550 quid.

However much it costs I'm sure that all that have had the mod done correctly think its worth every penny, its a big grin factor with the extra power that is not going to wear off for a while. It probably will if I keep the revs up and loose the MPG though . But the extra omph is there when we need it to overtake a bit quicker which is why I had it done.

I have heard a rumor that BMW can tell if a piggy back chip (alternative to re-mapping) has been used even if removed by checking the fault codes, is this true?, if it is will it affect the TLC. Only asking as a Friend has one fitted to his cooper

Happy days

A couple of things worry me about the graphs.

The resultion or smoothing is such that the power shown during the gear change is well above zero. It should be just about zero. The graph doesn't seem to get down to zero.

The standard engine produces 180 Nm of torque at 2000 rpm, which is about 37.7kw. Maximum power is at 4000 rpm and is 55 kw. I would expect the power to rise most of the time in 2nd gear, and then fall quickly beyond maximum power as the rev limit is about 4600 rpm. The graph doesn't show that.

I don't doubt that there is a big power increase with the re-mapping, but the I don't know if the graphs are totally accurate.

Nick made two trips to my home from Liverpool, So I guess he made a loss on this one.

I don't know how accurate the acceleratometer boxes or the software he uses is, but going from the results obtained over several runs it doesn't look that far out of 73BHP for the standard run which is what I would of roughly expected. Therefore the remapped version with the same parameters from the standard runs should not be that far off.

Regarding the peaks and troughs on the graph, I haven't a clue, its only the top peak I understand more BHP more Torque (I think, correct me if I'm wrong?).

Obviously a rolling road test would be more accurate but that would almost double my costs at 40 quid ago, and for the sake of pinning it down to the exact BHP I don't think I can justify it (unless anyone has one available free of charge) :D

The power increase as you say is very noticeable whilst driving, infact it's vastly different with a longer and faster pull through the revs which is what I was after. The wife took it out this evening after the work was done and noticed the difference straight away so I hope BMW mechanics don't when its in for the next TLC service.

If I have a K&n filter fitted and other mods done I probably will take it to a rolling road just to see what the difference is from standard, but until then I can only go on the graphs I have been provided with.

I will post regularly my MPG and overall impression over the next couple of weeks if anyone is interested

Happy Days

Thanks for the info Jay: a bargain by the sound of it!

Hi all

An update for you

Top speed on a flat on the speedo 112mph (obviously I found an unused airfield).

Original top speed 104mph again on speedo same road, not a great gain but the difference is really in the acceleration.........Woooooooohooooooooo

I will do some mpg tests over the next week to compare the difference from the upgraded ECU with the consumption I was use to when I stop thrashing it.

:D

Have you done your mpg tests?

hmm !!% out of mine and had to back off?

I saw 110mph on Sunday in my new one! Standard!

Raiderz,

Sorry for the delay been at the TT races for a couple of weeks.

My wife and I have now covered 2k in the car since the ECU has been done with no problems at all.

Filling up at between 530-550 miles per tank which I think is excellent as the car is still getting a good thrashing.

I would still defiantly recommend this upgrade as the first thing you add to your diesel, you will not be disappointed

Is there any firms in the NE of England that do this or any contact details for firms who will travel here for not a lot of cost???
