....or you could have your Bosch Motoronic unit live mapped to what ever specification chips you want. Thats only about £500-£600 done and dusted and will be a lot better then off the shelf chips because its done to suit your car, and its quite a bit less hassle and cost then switching to aftermarket management.
The Bosch ECU is pretty good, given half a chance at being programmed properly :beer:
Still has the airflow meter though then if you remap the standard one, plus if you make any slight change you cant adjust for it yourself and have to pay the money again, sod that!
yeah but the ciruit diagrams are freely available on the net now and i will happily say that i paid no more than £15 for the bits and that was paying a little over the odds in a maplinesque shop lol
Rodger - Im doing some more research at the moment. I have met with guys who can live map the Bosch Motronic chips, but not the ecu.
"Whats the difference???"
Chips - We can alter ignition, fuelling etc (and the boost levels if what I have been told about the amal valve is correct)
ECU - We can do all the above, plus add Traction control, Anti Lag, Turbo timer, Remove the A/F meter, alter the open and closed loop thresheholds the list goes on.
Ideally I would like to be able to do the latter but as its just taken us 18 months to crack the ECU coding on the new Renaults, dont expect immediate results! Being able to re-program the chips is a much more appealing option as the technology is readily available to me, I just have to buy it! We already have in our workshop all the GM tech equipment for fault finding and code reading as well as alot of the re-formatting gear for ecu's and the SE's most accurate 2wd dyno........... so I'm thinking that It might be a smart investment.
As for who re-programs at the moment, well, let me speak to them some more. If I reccomend them as a company (remember im a tuner and put my rep on the line every time I reccomend someone) then they need to be top notch (which im 99% confident they are already). Alternatively I might just buy their GM/Bosch mapping software off them and do our own live map service, hopefully for less.

Well if they work, ill have a set off you for 50 quid assembled mate, not worth me getting my hands dirty making my own or looking for instructions if you are knocking them out that cheap, just dont let alan at DTA know you are doing it or he will probably try and sue you!
Id still sooner have a brand new and guarneteed Y2K+ spec processor than a 15 year old moronic one with a new program on it.
I just cant see the point in spending 600 quid on new software for a slow ECU that has 15 year worth of rot already built up on the circuit boards that is just waiting to go wrong.

Yeah they're easliy makeable and cheap to boot. There's a guy on racecar that does them cheap too - username MEF. I bought my old DTA setup and TB's from Martin. He sells loads of EXP48 and P8PRO units, looms, boxes etc.
adjusts timing on 1 cylinder? does it have a little arm that moves the contacts in the dizzy?
the sensor isnt 'handed' either so it may be able in ideal conditions be able to sense 2&3 apart from 1&4, but it wont say which ones which so if anything it could retard pairs, but in fact it just retards
ah you mean because it knows which cylinder is firing at the time you mean?
Cant say it really interests me a great deal which cylinder is knocking TBH, you can soon see that from looking at the engines detailed log file (the plugs!)
All good though if it then tells you which one and saves you inspecting the plugs, do you need tech 2 or something to read it though, cause a paper clip is as sophisticated equipment as im prepared to buy just to interogate the moronic

Why would it need to move the contacts in the dizzy?
The timing is trigured by firing the coil, not by when the rotor arm is alongside the contacts, the rotor arm is alongside for about 60 degrees so is happy with any timing event within that window.
