mines ecu

[rx7veilside]

should be a very popular ecu..fully mappable for a fiver

ur flogging a dead horse rich

Apparently, lol

Let us know how u get on mate, details of ecu and who\'s gonna map it...

[carterjohn]

i will post all the details soon,i cant see waht all the fuss is about ive mapped my last 3 turbo charged cars,

Not trying to make you look like you haven\'t got a clue what your doing, we\'re are just trying to help as some of us have had years of experience working on rotaries, and have a better idea than most what works and what don\'t. If you want to pursue this avenue then all the best with it.
By the way rebuilds are approx £2,500

[carterjohn]

i appreciate the help,the ecu from the usa has a daughter board witch has a removable eprom chip,i allready have a chip writer and mapping software all i need is a rolling road and a wideband.before i start this are you saying it cannot be done?.im not being foolish,like i said i have done it before but as you say im new to rotary\'s

(should i ever need a rebuild i will be doing it myself)

I think the problem is, a lot of people buy these ecus from Japan and don\'t have the ability to reprogram them (which you obviously do).
Let us know how you get on with it, could be very interesting

Let us know how you get on with it, should be interesting

should be a couple of weeks,i will take a few photo\'s etc incase anyone wants to have a go  :Giggle .
chip writers are pretty cheap

daughter boards etc are also cheap

Make sure you shoot for quite low/Rich afrs on boost, Rotaries need a richer mix on boost then Piston Engines. And unless you uprate your fuelling system dont run more then 0.8 bar of boost on the stock twin turbos

[carterjohn]

thanks for the heads up blitzboy,any other info will be gratefully recieved.

ecu has arrived and yes it should be a very popular ecu as it is totaly fully mappable  :cool
plugged it into my eprom reader  and the map looked pretty straight forward.so i swapped the ecu\'s over and took it to my m8\'s garage to check a few things out with a wideband. A/F 11.5 at max boost,so a nice rich mixture there.went for a drive on the motorway and i was very pleased the secondry turbo come\'s in sooner and has more boost.i will take some more readings and post them up if anyone is interested.
all in the ecu has cost me £26

:cool

Fair play to ya mate. You\'re the first person I have heard of that has managed to map one of these in the UK.

I guess a good knowledge of processors and boards as well as a good knowledge of cars has got you where you are. Everyone else pays £100\'s for an apexi ecu and maps that, as you can directly access the ecu without boards or chip readers.

I think you deserve a ****ing medal or something.

ooh I dunno, this might be the holy grail of ECUs!

I\'m wondering who\'s said they can map it too

I think a little humble pie is on order around these parts.
