Yeah i here what ya saying Sydneykid and cheers for the reply.  I was talking to the local place that i got a quote off and he said that the Apexi Power FC unit that they get in is not capable of deleting the AFM, does this sound right???

Yes it does. There are a couple of PowerFCs. The entry model one, which is the most common, must operate with an AFM (on cars that had AFMs).

They do sell Pro versions (can't remember exactly what they're called) that let you remove the AFM and run it off a MAP sensor or something, but those are harder to come by.

Or this link from Greenline Motorsports on the types of PFC.

On topic, I'd say get the PowerFC. I'm not a big fan of piggybacks unless you're sticking to a light tune application, and there are a lot more PFC tuners than EManage tuners.

I was also quoted $1050 to me in Tassie with the H/C

Why the hell would you want to delete THE most effective method of determining how much air your engine is flowing at any point in time? A MAP sensor measures pressure, not air flow, the ecu then guesses (by maths) the airflow. It can NEVER be as accurate as an AFM.

I have seen Power FC equiped cars make over 1100 bhp, I have seen Power FC equiped cars do low 8's for the 1/4. Personally I have an R32GTST with a Power FC that has 420+rwkw and it runs better than it did when standard. We also have an R32GTR and an R34GTT and all of them have Power FC's.

All of those cars had AFM's.

Because you like kickin' it old school, pushrod style.

One of the most common modifications to LS1s, after an exhaust, is to remove the MAF (which is apparently a bottleneck, not sure if its because its "only" 90mm or for some other reason) and reflash the ECU to run on the MAP sensor.

The way I see it, removing your AFM and swapping to a MAP sensor makes you a "V8 loving bogan" ;)

If you didn't need an AP Engineering version then its a no brainer, obviously go for the Power FC, but with a price tag of $1500 it has to make you think twice. Why not just wait till you have done all the mods you plan on and then get a remap ?

all mods are done bar a FMIC and the ECU upgrade, so its not a matter of price, its a matter of tune ability and getting the best possible set up out of the car with the mods i have done to get the power that i am looking for.

$1500 for a PowerFC ?

i dont think so. More to the tune of $1100 with H/C as they now come as a package set

If it's not a matter of price, and you are only concerned about tuning ability then there is no competition, go the PFC

So the MoTeC units that are the racing world's most popular "off-the-shelf" replacement ECUs aren't even worth a look-in?
