VERY early first impressions ....Really easy to fit.....differences most noticeable at very low revs (under 2500rpm)But I do have a totally standard air intake which probably restricts higher rev 'action'....Summary "Turn your SPI into an MPi for 40 quid?!Bargain!"

Technical Cinq Sporting Performance Chip
I read that youre meant to disconnect the battery for at 45 mins...I fitted my new McCrich chip so fast it may not have been disconnected that long....Is this a problem?Excuse if question sounds stupid!Is ECU a separate item....I assumed chip was the brain of ECU so changing chip rewrote ECU automatically......

nah you dont have to at all, i never did and its all good

i never disconnected mine, just unplugged ecu, changed chip, plugged it back in and away i went, it ran like a bag of **** for the first few miles though until ecu did what it suppose to do

If you completely remove the ECU it goes back to factory settings. Not sure where the 45 minutes comes from. I think that with the battery disconnected the settings are lost almost immediately. The re-learning can take significantly longer than in the Haynes procedure. I have had users claim that improvements have continued up to 100 miles of mixed driving. Personally I think on my car the change is embedded after a 5-10 mile blast.
Hope this helps,

purely out of curiosity, how does the 16f ecu work? does that chip change the whole map or does it just give out a different value to the standard one for a given set of values entered? not that well up on the terminology, but i understand the concept.
Really getting into my new chip now after 80-100 miles .Definite performance boost at low revs.(And the air temp wasnt even cold today)Wondering if an air intake/filter mod might give more high rpm torque(but maybe at the expense of the low end boost?)
All in all a very nice "MPi" /diesel feel to the car now....!(would imagine top speed and maybe even mpg up too if I could stop thrashing it!)

When you create the chip, were you able to move the limiter up the rev range, or disable it completely, dont worry im not thinking of running without a limiter but have a seperate stand alone module complete with shift light that i intend to fit.

I dont think thius is too secret. It changes the whole map, mostly by leaning out the mixture as the standard chip keeps the mixture rich to prevent pinking from poor quality fuel. It advances the timing slightly in part of the rev range and richens the mix in part of the revrange.

I think a GSI type induction kit will increase the lower torque, and a freer flowing exhaust system will increase the top range revs at the expense of lower range torque. Well thats what I experienced with my cars, measured with my road dyno.

Its possible to do all sorts of things with a custom chip. But Its not really worth the labour cost to develop and test. I produce a standard chip to keep the cost low. Superchips charge £250 for their chip and that also a standard version. If you want specific mods to suit your specific tuning its better to get a piggyback ECU and have a rolling road set up.

On the standard car the GSR induction inmproved peak power by 5% and peak torque increased by 10Nm at 3100rpm.

Just my 2pence worth on regarding these chips. If you own a Sei (SPI) then get an Sei specific chip off of McKrich. I tried to get away with a Cinq one (running a Cinq ECU too) and it did not work as effectively as the Sei specific one does. Yes it costs a little more but on the plus side, you keep your imobilser which is a definate plus.
PS: I have a Cinq ECU (it requires a Mckrich chip in it to be operable)for sale if anyone doesn't want to tamper with their original ECU.

Been running a 'Universal' in my 98 Sporting for a week now. Must say I was quite please with the effect the chip had. Car pulls more smoothly through the low revs and I notice a change for the better in the mid range. All in all just about the best forty bucks I've spent in a while.

Despite trying everything, mine still takes 15-20 seconds of starter-turning to fire it from cold. I've changed plugs, leads, filters, ignition coils, engine temp sensor etc with no improvement. Swapping the old ecu back, it fires first time every time.
The chip is fitted correctly (I'm an electronics tech - don't dare ask if I can solder in a chip carrier) and the ecu is bolted in properly. The maf sensor had to be replaced within a day of fitting the chip, but it may have been on the way out anyway (detected with Snap-On Vantage scanner) and I have no other ecu error codes coming up.
Anyone else experience starting problems? I'm fitting my new head with Punto 75 cam soon and don't want the problem to get worse, but I like the Mckrich chip too.
Anyone?
