CP's Trackday 1.6 on TB's re-build

[Adam]

someone fishing for some business..... call me an old cynic

Now now, you cant say that



Jesus, that nearly escaped out the rollers,Lol. Does sound quite ill about half way through the rev range.
On my daily that developed a similar problem, like it had a rev limiter as soon as it was under load, but would then clear. That was down to a dodgy coilpack.
Ecotec btw, so uses the coilpack that most tb'd engines use.

Hmm think i would be going to track and road for a remap Charles after some of the stories and abominations i have seen about the other company....

On my brief drive I experienced the following:

1st lap, appeared to be all ok, lots of power and relatively smooth torquey delivery, far better than the 1.4 ever was. After a lap on full power something changed and there wasn't just a loss of power, the engine was dead. Depressing the throttle pedal dropped the revs and ultimately lead it to conk on my way into the pits, only just made it! The car idled well and after 30 mins of cool down would go out and do another lap or so on full power. What gets me about the mapping suggestion is that the fault is/was so on and off. I'd also say that each time its been driven, the time of good running is reduced. Anyone want to look at the map and data log?

So has the coilpack been swapped for a new one?

[Jim]

Not yet Will.

chuck it this way
Very much a temperature sounding issue, so either there is something stupid in the calibration regarding what happens with engine temp, or the coilpack is on its last legs, or the bay is heating up and dragging in such hot air that you lose power.

Unlikely to be heat soak (into the inlet) - I ragged my 1600 for about 25 laps in the summer and all that got hot was me!

[Adam]

Coilpack getting hot and cutting out IMO
Hopefully not the ecu coilpack drivers/amps

[lee303]

does kinda seem like its a weak spark for whatever reason, would also explain the dead plugs, did you find out what grade they were? i suppose you could see how the spark looks when its hot and mis behaving and compare it to when it cools down, no crank trigger errors on the ECU log?

Was only chucking in the unlikely possibilities
