Well some people have got a dastek unichip to work and there's a company in italy that sell a kit for the 100hp with full installation instructions.
I've mailed them, but I've not yet a reply.
I have a Dastek UNI-Q (+ what they all an iDriver specifically to fly the injectors) on my supercharged 1.2 8v 4x4 and it took an age to work out the pin-outs correctly. Fortunately I had the eLearn workshop manual, but I don't think that covers the 1.4 16v unfortunately. I fear you'll have to look towards the Bosch documentation for more info (the 1.2's run the Magnetti Marelli ECU).
The biggest issue you may hit (as indeed I did) is that the OEM ECU will possibly stay on CLOSED loop the entire time, meaning that it will solely use lambda for setting AFR's, regardless of what you might try to interpret and 'adjust' in the AEM Fuel Pooter. If the stock ECU wants 14.7 then it'll keep adjusting until it gets it. It was very hard to get the thing to run OPEN loop and use its 3D map in the ECU. This of course is how 'normal' remaps happen - tuners simply modify the 3D Map that is used when on OPEN loop and optimise parameters to make (smallish) gains as appropriate - leaving CLOSED loop untouched.
Most normal ECUs go OPEN loop at say 50-60% load/throttle and then no longer run off lambda, as the 3D map then provides mapped parameters. This is all well and good if you can crack the ECU to re-jig those 3D maps. But as JUSDEL says, the 100HP is very hard and none of us are entirely convinced it's ever been done properly. We fried one ECU in my car trying to re-jig the 3D map..... these things are getting much more tricky to do.
For what it's worth, we had to do a lot of jiggery-pokery with the power/sensor leads to the lambdas on my car to get the ECU into OPEN loop when needed, which is not ideal and I am still looking for an alternative in truth.
Sorry to ramble, but you started it!
