kenny had his car cammed at pugperformance, meaning his is not mapped. and his is fine???

is there any truth in what this company are saying??
i popped down there today, and asked about cams , he said you dont need a remap .
are they just saying that because they are not able to map themselves??

I would'nt trust Colin any further than I could throw him Dry

i've always thought the car should still run with cams unmapped just slightly rougher an idle abit worse than if it were mapped

personally i'd have it remapped

Those cams colin passes off as his design are just piper cams he buys in bulk and then etches stuff on them and they are pretty mild thats why they run ok with out a map.

Peugeotdave has a set of those cams in his car, once its built up and mapped will soon see how good or crapthey are

quite an interesting thread for me, considering cams if i know i wouldnt have to fork out over a grand for them to run.

thing is, my engine has been skimmed after a belt snap and im worried abut how lairy i can go with cams. id probably go with piper cams as i live 2 seconds from the place. any advice?

Closed Loop - An O2 sensor is used to monitor the air/fuel ratio and is used primarily under cruise conditions at light throttle opening (generally below 25% throttle opening) to achieve air/fuel ratios within a predetermined window of values. Ideally lambda 1 (14.7:1 Air Fuel Ratio). The standard ECU trims injector duty cycle (amount of fuel) only and does not trim ignition advance in closed loop

Once the ECU is out of closed loop,IE Foot Down, it reverts to predetermined fuel and ignition tables. There is no or little learning facility in this mode. It is very easy for you to bring the ECU out of closed loop. A light stab on the throttle will bring the mixtures outside those able to be monitored by the O2 sensor

Says it all really , will f*ck your engine over time. and wont get much improvement

its quite simple. you get uprated cams in your car, you get more power. if you dont get it mapped, you may gain, say, 8 bhp (dependant on cams) whereas if you do get it mapped with stand-alone ecu, you can look at gains of 15-20bhp+ with smoother running and better mpg than if it were not mapped.
As said above, why get cams but not get a remap??? pointless! You get what you pay for. Wink

His should make more power as his C/R is increased and with those big valve cutouts he will safely be able to run with more advance than the guys running standard pistons.

collin seems lieka sound bloke, but people take him the wrong way. i have herd equal amoutn of stories abotu pug performance and collin and i think i would give them a go. the piper 270 cams dont need a re map as the standard ecu can cope. i fuel pressure reulator is advised to produce the ectra fuel. collins rally is runnign this and so is ollies gti-6 , mine will be shortly as im goign down this route

collin does not havr the mapping facilities on site but he does use a local place to map his cars. obviosly he belives that you dont have to mapp them on this set up.

Well you take your chances then, he does have a reputation for ripping people off, and I'm making no accusations but I have heard a lot of stories about parts going missing from customers cars left at his place. I certainly would'nt leave a car with him for more than it takes to do the job and go. He knows his stuff, and if he likes you you may be treated ok. Personally I would'nt touch his place with a barge pole after some of the stories I've heard.

If you look on the piper website they say the 270's dont require mapping but the 285 do.

Hi all... Got my 6 back yesterday sporting all new goodies, including the pp head and piper 272 cams in question...
Finally got to go for a decent drive today, and I'm very impressed! I have noticed a definite increase in power and throttle reponse...
I'm getting my car valeted on tues, so I will get some pics and start up a newbie thread!
Also got a power run on tues also, which will be interesting Smile

Thanks for the help... She's running awesome now!

are these the piper 270h cams. I take it you gave pug performance 600 quid and for that you got a longmans head and cams. i will be doing the same setup but might have to get collin to supply the head as im gettin a mate to do the work

you DONT need it to be mapped, if anythin its other companies tryin to get you to spend more when you dont need it, granted you might gain a little from a map. If all there companies say you dont, it means you dont

^I'd always remap with a different cam, you tend to end up overfuelling down low and running a touch lean up top, the exact place where either will do the most damage...
Can I ask where it says a remap is not needed in the Piper catalogue? Because as far as I can see, it doesn't.

Well thanks for the highly technical contribution...

Your engine would 'run' with 320* race cams in, badly, but it'd run...

why would you not map them for cams? losing out on bhp there.
