I haven't been to this site for a while, so I don't know if this has been discussed yet but I'm interested if anyone has tuned their car first with a PFC, installed cams, then retuned their PFC.

The reason I ask is the MWR dynos of the PFC and cams are good, but I have seen cars with only tuned PFCs (including my own) put down close to the same WHP.

Anybody try this yet?

No-one I've seen. People were clamoring "we need cams" for years, but I don't think too many sets have been sold...

last time I looked into ordering them from mwr, they had to order a certain # of sets and those were all locked in around 870-900 something per pair of cams. There was also a long wait for them to be shipped over from europe.

I figured sometime a groupbuy would eventually start up, but it seems the interest just fell away....

It wont take Pipercams more than 1 week to have them flown over depending on what service they are using and if customs are being boneheads or not. I've had items from the US arrive within 2-3 days normally takes 5 - 7 days +. IMHO minimium orders put customers off from purchasing. Thing is to remember cost of sending from the UK to the US is alot more than, for you guys to send itmes over which is alot cheaper.

yeah it was the whole minimum order requirement that kept me from jumping on the first day.

I might dig back up the results thread from MWR and start seeing if i can draw more interest back into the cams.

I think some guys bought them but dont post here. I guess we are all waiting for a "guinea pig" to test them and bring more independant dyno results! And also, there r the ones from Ragnorak racing ...

Bolt-on (if no shim adjustment needed like MWR pretends) would be an easy install. However, if we r able to change springs w/o removing the head at the same time, it would be better. I'd like to make sure we can do that be4 to jump on cams!

Ya, you could probably change out the cams in a couple hours if you just had to pop them with no adjustments.

I have the Piper cams stage 2 fitted to my car. Best upgrade I did so far. Idle isn't wobbly at all once the ECU got used to them.

So far the only downside is that the car has NO torque AT ALL under 3.000 RPM. When gooing to work on a hot day (so with AC activated and an cold engine) it is virtualy impossible to get off the line without revving over 3.500 rpm or it'll stall. This is all beter after 5 min of driving, so no serious downside.

Power gains are quite noticeble and the exhaust note is really different. Most people think I'm a bike when blasting by @ 8.000+ RPM. (full inox catback mandrell bent). Lift kicks in much smoother wich is less impressive to drive but that was to be expected and it has made the car a lot faster on daily driving. In practice the power band expanded from 6.300-8.300 to 5.000-8.300

I'm a crappy driver but my 1/4 mile time went down from 16 to 15.3 only with the cams. This was measured with a G-tech in similar conditions.

Since i drive a corolla in stead of a celica i did not yet find a good sollution to modify the ECU (power FC wont fit easaly + ultra expensive over here and no one to tune it) but i definetely feel there is a lot of power left unused with the stock ECU. I'm considering the Camcon because it seems reliable to alter the valve timing but i'm not shure it will help me that much.

What would be the best solution concidering power FC is a no-go and budget and reliability are more important to me than max power. The 2ZZ-GE is verry rare here so most tuners have no id what the possabilitys are.

Ow, it definately feels like the engine would love more RPM, the power keeps building up until the rev limiter kicks in. 9.000 RPM shurely would make even (alot) more power ...

Orbit how did you find the install, was this done with the engine still inplace but with the rocker cover taken off, any hints and tips for people thinking about doing this mod thereselves ?. Have to admit the 0-3000rpm loss does sound suspect, perhaps the PFC or Camcon will over come this. Have you managed to get a DYNO done also ? just to see whats happening on the rollers.

yeah i take it by the "idle was fine once ecu adjusted" that you are still on the stock ecu. Tuning with an emanage or even upgrading to pfc would eliminate it for the most part.

Well, i didn't do the install myself, i'm not really that handy so I had a verry well known local tuner do it. The man specialises in BMW and VW but installing a cam is installing a cam, whatever brand the car is. I stoped by while they where installing and they didn't even removed the strutbar I have. For so far I could make up they only needed to open up the valvecover.

It took them 2-3 hours to do it, mainly because they never saw the car before.

I'm planning on dooing a Dyno run ASAP but i'm a bit unshure where to go.

I have a well known tuner that does it for 60

if you have lotus tuners near you regardless of the price i would be knocking their door down for help.

if you end up with a pfc, those lotus guys might make you one hell of a map (then you could share it with all of nc.org :) )

let us know what you end up doing, cause i want those cams your running but i have to tune around them if there is that much torque loss.

The torque loss is really only when cold, once the engine is up to temp it runs fine. It is really just the first 2 miles that it behaves like this. That shouldn't stop you from mounting them. I have the feeling that when cold it realy runs WAY to rich. Also my exhaust 'bangs' every time i shift when it is still cold.

It is just anoying I cant contact Alvan right now, if he doesn't have a spot this thursday for the dyno it will be weeks before I have time to do it :(

Anyway, i'm pretty shure I won't do the Power FC because i do not want to lose some of the functions my car has now like ABS, VSC and Traction control. And ofcourse, as much as i love this car, it wont be mine for the rest of my life and the big bucks are reserved for when i drive a car thats faster to start with and has more support from the local tuners. Although I do not really know a car that i would like as replacement of my corolla. It just al depends you know ... For the moment i would just really like to get the tune that slight bit beter than with the stock ECU just to get the most out of the mods i've done.

And after that, time will tell what happens. After all, with the rising gas prices (1.45

The PFC doesn't take away ABS, etc. Those work independantly from the ECU.

Are you shure? I understood you guys don't even have TC or VSC in your GTS's?

Since VSC and TC limits the power of the engine I don't see how it can work without at least co

I definatly still have abs with PFC. no traction control tho :gap: Not that I mind honestly ..

go with the hydra ems. they have a model for the corolla. i have the camcon and am going to attempt the cams with it. hydra runs for $1500 and the camcon runs for $330. the only big difference for the tune is the lowering the lift part. Also our corollas have more wires running to the ecu. i dont know exactly what there for. 1 must be for the smog pump, eliminating that will allow you to install the race header. good luck!
