rolling road 172/182

[Big Iain]

Ok anyone here that has a 172/182 with a full system on the car and had it rollin roaded???

jus curious to see what power gains you have had??

 

[wackojacko]

Yeah :-(

Mine made bugger all. (ie I lost about 10BHP) Got a full SuperSprint system with De-Cat was running much too lean under full throttle/load.

After I get it chipped (if i keep the bloody thing for that long) I should be running very decent power.

Although I think It might have been because my Oxygen/Lambda sensors were pluged up wrongly giving the ECU bad signals

 

[Big Iain]

hhmmmm dont say that!!

so to make the best of the decat filter and full system I may need to get it chipped??

 

[McBunny]

mine gaind about 10-11 bhp with the same exhaust well the bigger version

 

[Big Iain]

I have the K-tec twin 3" with a janspeed decat goin on this week and a very kindly donated green filter too!!

what can I expect??

 

[McBunny]

erm maybe about 7-8-9 bhp maybe going towards the lower end due to the pipe work been smaller

 

[Big Iain]

180 hopefully then?? wat is that roughly at the wheels

 

[McBunny]

looking at 148 ish

 

[wackojacko]

Yeah i cant believe the difference between mine and Dogmauls.

Thinks its because i was a fool and left the second sensor pluged in which must have been give the ECU dodgy readings. I#ll have 2 get it on the rollers again soon.

 

[Big Iain]

ok so you dont need the second sensor???

 

[wackojacko]

No just the first one.

 

[Big Iain]

so what do you do with the other sensor??

can anyone else confirm this??

 

[wackojacko]

The other sensor goes in your garage.

Know one has come up with a definate answer as to what the second sensor actually does. I would like 2 know.

What signal does it send to the ECU if unpluged (left open circuit)?

 

[Big Iain]

I dont know weather to cancel this cat pipe or not now!!

 

[wackojacko]

PM Dogmaul hell sing the praises of De-Cat pipes.
