The Superchips M135i piggyback ECU thread

Post by Mike Roberts » Wed Jun 19, 2013 9:11 am

Seemed a good idea to get a dedicated thread for this, seeing as it's split over a couple of topics.

Feel free to add questions, good/bad reviews, info etc. here:

Key facts
£399 during offer period
+49hp
+104nm
Stand-alone ECU that plugs into OE sensors
Retains OE map, so linear delivery characteristics are the same, just with an x% increase
Plug & play 5 minute install
7 day returns policy
Can be sold on once you're done
Full warranty cover of box in the event of failure (see their website)

This is not a Bluefin OBD flash type device, it's more similar to the Hartge/JB4 style piggybacks. It has been developed in conjunction with another well known company and has Superchips' own settings based on their development time.

Superchips website

There's going to the usual dyno debate, but I think it's widely accepted that the car makes an average of 340hp as standard and is quite sensitive to fuel. Sedox seeing a significant increase once he'd ran through some V-Power over supermarket 95 it was first tested with. (I'll find the 2 graphs)
Given this, I think either this was a very healthy car, or it's over-reading by 15hp, so taking that into account your expected power is at least circa 385hp. We'll obviously edit this once people have them installed and verified on other dynos...

Manual car done in roughly 10degree ambient temps. The car was fully logged for AFR/EGTs etc both on the rollers and the road for a long period of time, it has also been subject to months of daily use. I don't believe it has been on track yet, but I can confirm.

Thanks for this. I have no doubt there's going to be a lot of downunder interest in this.

Does anyone know if it is country fuel specific? "Retains OE map" seems odd to me

What octane fuel do you have in upsidedown land?

Retains OE map = the factory BMW ECU settings and 'map' are not altered or overwritten, as they would be with a traditional re-flash. Whether BMW could detect the car has been running more boost/timing/fuelling I don't know, probably if they looked hard enough, but it certainly won't flag up it has a different map or someone has tampered with the ECU and start alarm bells.

My main question: does it de-limit? I'm guessing not?

I don't think so. You may be able to buy the N55 SDL from Burger and do it that way?

So Brooklands Horsepower are in Byfleet (like me) but seem to have a pretty poor reputation.

Scole Engineering are near my parents and have an excellent rep, so they'd be my preferred choice. However I am yet to ring them so don't know if they'll be able to do it, I also haven't rung Admiral to see what they have to say about it, neither am I sure that I can get over to the parents that weekend.

As you can see, it's a very well thought out plan :roll:

Am I right in thinking you're in Sunderland?

That's a excellent offer. Hopefully someone will take you up on that asap as very keen to see results.

Yeah, Crawley or Reading are both easy enough to get to.

No, it's someone I know who's a bit off the radar when it comes to forums. I kind of know the MD of Superchips too, so have been kept in the loop.

For now, I am sorely tempted...
