MG ZR: Cams & Maps

[procta]

Stopped off at the rolling road place/garage on the way home last night and ended up chatting away with the oweer til after closing time. He's interested in seeing what can be done with the mapping as he's dabbled in it before but with live mapping software and aftermarket ecu so a bit easier to do than read, write, repeat. He also had an old MG B in there getting a reworked engine along with some jap drift looking car.
I'm really enjoying learning to do the mapping at the moment as part of the fun being that since so few people touch there ecus there's very little help in the sense of guides or people going yea that's that. Having to figure it out myself and I might be wrong which is keeping my interest as I'm having to keep looking back over it again and come up with new ideas.
For example I thought I had the duty cycle sussed out through calculations etc but forum lot are saying their mg tf s at 170 hp are running 85& duty cycle about the limitn of the injectors whereas I'm finding the stock cycle to be about 60%

I think the Mems 3 never really got the chance to be played with sadly, as with rover going out like that, the sport side of things went over too, which used to do the performance side of things for the Rovers. A bit of a pain in the arse that its took nearly 10 years for someone to start to play with the Mems3 properly.
the thing with these is the pressure regulators, you can play that you know, As they used to swop that with a programmable one. Not sure how much they are, but that will help you with the fueling side.
Also the metro cup lads were starting to run the mems 3 units, too I think I told you? Now they have had to revert them to emerad ECUs, as there was a bit up roar if the mems3 unit was giving people the upper hand mapping wise.
You really need to get your arse down to a MGCC round and talk to the lads in person about these. They will be more than happy to talk to you. They were well helpful to me.
