Detonation/need tuner for Power FC

[barryogen]

So, driving home last night giving the car a few beans, the little "check engine" light flashes, which as I understand with a power FC means that pre-detonation* is occuring.

A "soft" drive to the nearest gas station and a bottle of octane booster got rid of the flashing light for the moment, but I figure that a re-tune should probably come sooner rather than later.


Around Dunedin, is there anyone suitable?
I have the little hand controller, but I understand that they are a pain in the proverbial to use to tune it, so I guess I'm going to have to shell out for an "FC Datalogit"? either than or the hand controller isn't too bad, and someone can just retard timing, or add fuel until I can get it tuned properly in chch in a few months.


*not sure what it is, but I'd imagine that it leads to detonation which is bad mmm-kay

[cozmoid]

yes pre detonation is bad mmkay. Just try running it on 98 octane till u get it tuned properly. And i would ring around to see who might be interested in tuning it? I would say mike lim at the turbo shop would have no problems, also rob at total automotive might be able to tune it on our dyno? But seriously just run it on 98 and get it tuned asap! Detonation = killing engine!

Get it tuned asap, you don't want to have to shell out for a re build, or throw the stock ecu back at it till you have enuogh coin to get the pfc tuned correctly, pfc hand controllers are about as usless as tit's on a bull

spoke to a few mates over the last day or so, and we sorted it out, retarded a bit of timing, added a bit of fuel, and dropped the thresh-hold for knock from the factory 70 to 45, so it is now more sensitive to knock, but it's not doing it.

Am chatting with nzefi about booking it in for a proper tune.

It appears that it is running the factory Apexi tune, tuned for 104 octane, hence the knock issues.

How long has it been knocking for if that's the case?

I assume the previous owner didn't have a ready supply of 104 octane on hand

It has been running 98 with octane boost since hitting NZ, the only reason I put 95 in it, is that I was out of gas(dodgy gauge).

98 with octane boost fixes it.

[barryogen]

10L of c16 and the rest filled with 98 has "fixed" it for the moment

Put timing back where it was before, and dropped fueling back to where it should be, it goes a hell of a lot better.

Will keep doing this until I can get to NZEFI.

Booked in for June 6th.
Have been told to expect 4hrs tops for the tune, at $118/hr.

[barryogen]

leaving tonight... Just thought that someone should post something in the Dunedin forum... holy carp it's quiet, must be the cold.

[MasCam]

Good luck, let us know how it goes as if you wouldn't

[barryogen]

well, I'm at my folks, they have no scanner, and I left the dyno plot at home too...

It is ~160ish HP, up 10ish on what it was, but decent gains from idle up to 2250RPM, and 3000RPM upwards.

Will post the plot tomorrow once I can.

[barryogen]

I'm very happy with the gains through the rev range, overtaking is no much easier, and fuel consumption on the return trip appears to be far less(14%) than the trip up there, even with a head wind on the return... and I was driving considerably harder on the trip home.

Oh yeah, tuned on Shell V-power(their new 95, co-developed with Ferrari... yeah right)
