Had my ECU (mems 3) remapped (pics)

Well I went over to Rally Matt's on friday to get my car finished off. After the 1600cc conversion, it wasn't running to its full potential on the standard 1.4 map.

Mark, the guy who mapped it was one of the original guys at Rover who wrote the maps for the MGR range. He is currently working on mapping the supercharged 5 litre Jag's so I knew my car was in safe hands

Couple of pics:





Now if you remember back a few weeks to the red 25/ZR demo car that was for sale on ebay that most people dismissed as not being real, well it was as Mark rolled up in it. Unfortunately I don't have any pics of the bay but there was lots of equipment still on the engine bay (like pressure gauges) from when the engine was on the test bed. For a 1.8 K series turbo, it sure flew too Now Mark has the map from this engine, anyone thinking about turboing a K should give him or Matt a shout.



Overall to sum up a rather technical afternoon, most of which I didn't understand, the car is much better. It now has more power on full load, much sharper throttle response and is fueling correctly for the engine capacity.

Couple more pics:





Sorry if some of it doesn't make sense - I went out for my birthday las night and it was chaos I'll edit as I sober up.

Thanks to Rally Matt again for arranging this for me and getting an armrest bracket for me too as a birthday present haha!

Looking good bro. I can vouch that your car really does benefit from having the map. The map has definitely sorted out your flat spot and made it far better than when it was running a 1.4 map. A must for anyone with the 1.6 conversion.

Sounds good. What map is it running now though? Is it a standard rover/mg map or are you using a standalone ecu and custom map? Only asking because I'm curious.

Its using the same ECU with a completely different map on it. Its got a modified version of the standard 1600 map to give more power and also better fuel economy.

Because he his the guy who wrote the original maps for the k-series at Rover back in the day, he has the software and knowledge to remap the mems 3 specifically for your individual car.

From looking at the car with the map on he was able to see that it was underfuelling, clear any fault codes and also remove some of the parameters that a standard map has because the original maps for the car are a bit 'conservative'. I now have a quicker throttle response and more power on full load. I also had an idling issue where you blipped the throttle and when you lift off, it would dip to below 1k rpm. Thats now fixed and the car is very smooth to drive.

I need to get it dyno'd soon to see what it is putting out but he thinks it will have gained approximately 8-10hp.

Anyone wishing to have a go in the car is more than welcome if you fancy a trip to Oxford

Pretty sure its bigger pistons, liners and few other things into the 1.4 block.

I'll have a quick dig.

How do we get in contact with this fella? He seems a bloody handy geezer to know if you own a ZR. Shire, are you bringing your car to Fast Show? I'd love a ride in it.

Id like to know this as I have a spare block in the stores at work from when I killed my last head.

As far as I'm aware of you just need to put in 1.8 Liners and Pistons to make a 1.6.

Not 100% sure about the head though, if the 1.4 head works I dunno, someone else will mention I reckon.

(but if you change the crank + rods as well it makes the 1.8.)
