idleing

7th July 2010, 15:41

will a re-map sort out my idling issues??

the car is a furio with a vtr inlet on camed

7th July 2010, 16:27

I would have thought so

7th July 2010, 16:28

i thought you were dropping a bigger lump into it?

7th July 2010, 16:45

I don't think anyone knows what he's doing with it

tbh i dont think he does either

7th July 2010, 16:48

lol, what idling issues do you have ?

7th July 2010, 17:23

iam keepin this lump just get it running well

eratic idle and stalling, i have changed the icv and tried the map sensor out of the furio and the vtr

7th July 2010, 17:24

throttle position sensor, crank sensor?
But yeah re-mapping could help

7th July 2010, 17:27

ive messed about with the tp sensor still the same
crank sensor i havnt changed so unless that has broken at the same time

worth a go before shelling out on a remap mate? lol

Is that not down to the camshaft profile? And how it's timed up?

is it on standard timing marks?

I'm under the immpression/it's my view that cammed cars (right on the limit of an oem engine) on standard inlet do stall sometimes as the idle valve can't catch the 'idle' as you close the throttle and put your foot on the clutch coming upto the junction?

^ I suppose timing and mapping would help this.

7th July 2010, 17:34

ye? thats what i wanted to hear

this is what i thought due to it being tuned so much more than what the oem ecu is up to

7th July 2010, 17:38

so... best place to get an adjustable cam pulley?

7th July 2010, 17:49

yes, get an adjustable camshaft pulley, and get the cam timed up properly.

Unplug your battery overnight, then the following morning, start the car up with it all timed up properly.

The Ecu will 'relearn' the engine and it should be a bit better I'd hope.

Urm............ Baker do a adjustable pulley? KentCams? Catcams maybe? Piper ?

7th July 2010, 17:51

ill get it adjusted and mapped at the same time probly best isnt it??

7th July 2010, 17:55

what cam you have?

wellllllllllllllllllllllllllllllllllllllllllllll

depends tbh.

with the 16v engines, the single plugs seem to run fairly okay with the 708s/BP285s when they are timed up on standard ecu.

Depends on how flush you are ?

I'm always skeptical on people 'mapping' cars as sometimes you're better off with the standard map and parameters, and let the ecu adjust things.

How much for a remap on yours? I'm surprised they can remap and furio ecu? How they remap it? Put a re-writable chip in the Ecu, and write to that?

IMO, if I was you, I'd get the timing setup to the cam specs and try it out then to see if it's any better - if not, then get it remapped on the dyno.

catcams fast road cam is init (cant remeber the numbers of it)
sanspeed said it would cost 250£ and would be mapped on a rolling road not sure on what they use to be honest

ill get a pulley and get it timed up

...

Noob question....
would it have to be rolling roaded to know how to time it properly? or do i adjust it, start it, adjust it, start it sort of thing?

7th July 2010, 18:12

you adjust the timing to a certain amount of lift at TDC, or the degrees after TDC that you have full lift. You'll want to know how far you can go/valve clearance when looking to time it up.

I'm sure then, that the mapper will do a power run, tweak the cam and do another power run and compare - maybe in some sort of iterative process to try and find the most power/midrange/torque etc.

7th July 2010, 18:14

so would still need to be done on a dyno

basically its like mechanical mapping just advancing/retarding the time in which the valves are fully open

7th July 2010, 18:50

Normally the cam spec timing is pretty close so you can run it without dyno time and it's normally fine.

You only tweak it on the dyno for max power/torque etc.

£250 sounds cheap btw for a remap and timing tweak on the dyno

7th July 2010, 19:02

Just don't get ripped off with this 'remap' - they even going to touch the cam timing ?

7th July 2010, 19:28

to be honest i havnt properly asked... i just wanted it done lol

i will have a proper look into it
