Frankly?....nahfeel a bit robbed as it goes.
Have had the car down at Millway Coachworks in Andover since Monday, and the car was ready to collect, so off we toddled today. Its a long trek, and weirdly there is a Uni Chip dealer in my home town, BUT Dastec UK (Unichip distributor) suggested Millway for the best service.
My instructions to them: Its a rally car, MOT's aren't a problem, nor is fuel consumption. I want reliable power please....and the rev limiter to go up a bit.
Important note before we go further: Rolling roads are notorious for all reading differently.
I have had my car on 2 roads, onin Aylesbury, and one old one, owned by a trusted classic rally car bloke, in Huntingdonshire. Both said 108bhp. My firiend with the Nova GTE has been to the Aylesbury rollers and was gutted to find the other place he uses (Slough, Novatech) had been over reading by comparison....so I imagined my two reading were consistent and conservatively trustable. Besides, a standard one of these engines was 100bhp.
Also had both other roads do a speedo test, cos I know it over reads..both came back the same, 87mph in 5th at 6000
Imagine my suprise when Millway told me I had under 100bhp on it before modifications by them, and it topped out at 81mph!!!
Oh well...a bit of string can ONLY be compared to another bit of string on the same ruler, so disregard that . I wanna know what their road tells them before AND after.
OK, on that presumption, and lets not irritate them by a stranger telling them their road is miles out.....let them get on with it.
SO what did I get back. Well, the rev limiter is sorted, and goes plenty higher now...not that it manages it with much aplomb above 7000, BUT I knew that already...I just wanted a fraction more for emergencies, when a gear change is a waste.
Sorted. New ECU chip to up the limit and then use Uni Chip to limit it. Cleverly, the limiter is NORMAL under part load, SO if you sit still with your foot on 70% throttle in neutral, it will cut at 6400. It only revs higher with full throttle, when fuel is in there, keeping the pistons safer. Pleased with that.
So what am I less pleased about? Well it all RELEVANT. The roof of my house is high, but not RELEVANT to a 747 flight path.
And a gain ON PAPER of 5 or 6 bhp, representing about 8% increase is ok I guess.....and it IS sharper..but not what I hoped.
I DIDN'T hope for flames, I didnt hope for neck muscle strain, but I DID hope it would'nt miss fire on the way home!!!!
And it does.....and it only did it 3 miles from home....2 hours from Millway.
I think its a plug...so new will be in by Monday, and as I discussed with Jiff (my Moral Support Officer, who keeps my Car Feet frimly on the ground) I will do a fuel pump too I think, to be sure its up to the job....
but I had HOPED, maybe, with all the money I spent, they would have put new plugs in for the final test. After all, they DO fiddle with mixture A LOT, and must kill plugs daily.
How much was it? Well for me, thats the crunch...and it crunches like a filling coming loose in a cake you have just bitten deep into, and it hurt a bit
Unichip is: £255 plus vat
Rev limit Module: £50 plus vat
Supply, fit and configure Unichip: £80 plus vat
Full Mapping session on dyno : £95 plus vat
Wire in Rev de-limiter, set fuel pressure and cam timing : £76 plus vat
Total.......£618.05
So...in essence...you can get other stuff for that dough.
Live and learn hey?
