145bhp(flywheel)@6400rpm
137ft.lb@5000rpm
I know its from a different RR, but just setting standard figures. Do you have a standard RR printout before the work?
My 2.0 HDi was remapped to 115bhp but had 195lb.ft of torque, that would pull you back! I'm really dissapointed for you Edward. Despite the RR figures, i would have thought you would be able to 'feel' the difference.
#242: Re: Project sleeper Author: Edward, Location: In the garagePosted: Thu Mar 18, 2010 3:57 pm ---- You can feel the difference at really high revs i.e. between 6k rpm and 7k rpm. Waiting for the engine to get to those revs though is slower than standard!
#243: Re: Project sleeper Author: Steve206, Location: UKPosted: Thu Mar 18, 2010 4:09 pm ---- So odd, doesnt really make much sense?! Like you say, you would really expect it 4k onwards, its nice to have that power, but not much use unless your planning to drive around revving the engine so hard.
#244: Re: Project sleeper Author: Schumi, Location: Istanbul / TurkeyPosted: Thu Mar 18, 2010 4:24 pm ---- Do you want to use this car every day ? How is your idling ? Isnt it to lumpy for daily use ? I think with 285 cams power come at 4500-5500 rpm. Its so normal. Maybe it can be a little changable with cam timing. And I suggest you 17-77 (4.53) short ratio gear set. Its from 307 HDI. It will complete change your cars acceleration.
#245: Re: Project sleeper Author: gti180boy, Location: StaffordPosted: Thu Mar 18, 2010 5:00 pm ---- iv been reading this post now for a while and i love your car edward you know, looks oem from out side and even undoor bonnet just how i like mine.
i agree with dave you should take it to paul @ rs tuning and get him to check the map or even remap it him self am sure he will push some more torgue lower down out of it he can do wonders.
and i would get your cams timing check, and see if you are getting the most out the verniers?? i just had a cat cams vernier pulley fitted to my gti 180 that was ment for the gti 138 exhaust camshaft and slightly retarded it 3-4 deg and mine now from 4500 -to- 6500 pull like a bit-ch cant belive iv been driving round with cat cams wasnt getting the best out them intill now.

#246: Re: Project sleeper Author: Edward, Location: In the garagePosted: Fri Mar 19, 2010 2:48 am ---- I do wonder if use has been made of the vernier pulleys. I was never asked if I wanted good torque or big headline bhp figures. I checked again earlier and it goes quite nicely at 6.5k rpm to 7k rpm but it should be pulling like that lower down the rev range too.
Look at the time the print out was made. 6pm on Sunday night. Could it be there wasn't enough time to do a thorough job or mapping the whole rev range?
It idles about 1000rpm so sounds like a big motorbike when they are idling. It's quite a smooth idle.

it should start pulling aleast 4500 on ward early whats the point in pulling for 6500 to 7000 revs it useless i would get your cams adjusted by the verniers on the dyno to see if can get more low on power.
and 1000 idle is abit high really no need for this. i dont think they done the idle map properly or it wont idle at 750-800 and they rised it to cheat.
#248: Re: Project sleeper Author: macj, Location: EssexPosted: Fri Mar 19, 2010 1:50 pm ---- Asd I said to you before. This is a muddled mapping job. I think they bit off more than they could chew and ended up rushing it through for your collection on the monday. The fuelling in the midrange is probably way too lean and they have not utilised the valve timing to move your torgue curve around at all. It should be a mirror image of the graph and smooth.
You will get a shock when you get it back on a decent RR with an experienced tuner.... take my word for it... You will smile again then
#249: Re: Project sleeper Author: Tarmac-Terrorist, Location: West YorkshirePosted: Fri Mar 19, 2010 3:13 pm ---- If ecosse havent provided an AFR graph then I would be suspicious about the state of the map. As said, 1000 RPM idle speed and the timing of the graph all indicate a rushed job I believe.... Id have a word with Paul @ RST and see if he can shed any light on the subject...
The power band can also be tuned with different length trumpets.... Perhaps the box arrangment might have something to do with this?
#250: Re: Project sleeper Author: Jamie, Location: Ring y0Posted: Fri Mar 19, 2010 3:34 pm ---- I've already asked if he's tempted to go down and let Sandy get his hands on it!
Paul, this is one of the many engines Sandy has built;
#251: Re: Project sleeper Author: Edward, Location: In the garagePosted: Sat Mar 20, 2010 6:20 am ---- I'm going to keep the car as it is. The chances are the map is password protected anyway so a remap would require a total mapping session from start to finish. There is nothing to suggest the map is wrong in any way it is probably just the nature of the engine now.
It was playing up yesterday, when driving the car cut out very briefly (for 0.5 seconds) like a really big flat spot and then when rolling to a junction I saw the rev counter drop to zero then flicked back to normal. I didn't feel a change to the running this time.
When I got home it wouldn't idle and when restarted would run for two or three seconds then cut out. It then wouldn't fire up at all.
After leaving it a few minutes it ran again and I noticed when the high beam was switched on the engine would cut out. There is plenty of power in the battery otherwise it wouldn't turn the engine over.
I got fed up with it and left it overnight. This morning I switched the car on and it ran fine, no cutting out with all the electrical equipment switched on. It did give an interesting crack from the airbox when i pressed the throttle though...looks like it spat back for some reason.
#252: Re: Project sleeper Author: Jamie, Location: Ring y0Posted: Sat Mar 20, 2010 6:24 am ---- Please give ecosse a ring, they have obviously messed something up! Ask them to pay for a mapping session at rst for you?
#253: Re: Project sleeper Author: gti180boy, Location: StaffordPosted: Sat Mar 20, 2010 7:12 am ---- i would take it back it does not seem right and its just gona make you hate your car.
am sure ecosse no what they doing i would take it back and tell them you aint happen and tell them how you wont it to drive.
#254: Re: Project sleeper Author: GazRG, Location: Bournemouth/CardiffPosted: Sat Mar 20, 2010 7:17 am ---- For the money you've spent shouldn't you be happy with it?
Why don't you complain to Ecosse? That's the first thing I'd have done.
#255: Re: Project sleeper Author: Jamie, Location: Ring y0Posted: Sat Mar 20, 2010 7:51 am ---- Definitely, think how much money you spent with them!
If you bought a sofa from DFS and when you got it home it was ripped or stained you'd take it straight back wouldn't you!
There are so many signs that it was either rushed or bodged, give them a ring!
