motec vs Power Fc

MoTeC M4 is worth around $2200 without any options.

In terms of idle quality, build quality and performance, Power FC and MoTeC are on par. The advantage that MoTeC has is that you can configure it to do more things - such as control a shift light, run traction control, wideband lambda, and in extreme cases use it to trigger and air shifted gearbox...

In my opinion, PowerFC is ideal for a street car and most weekend track cars, but for a more dedicated race car that needs laucnch control etc, etc... go for the MoTeC.

The probblem is that the M4 is designed with 4 cylinder engines in mind - it only has 4 injector and ignition outputs. For a 6 or 8 cylinder engine, you need a M48 or even metter an M800..

Cheers,

Matty

Hi Maxx, whilst MattSR is correct, you can still run a 6 cylinder car with an M4. You just parallel up 2 injectors and 2 coils and thus use 3 (of the 4) Motec driver circuits for each of igntion and injectors. Very common way of using an ECU. The results are very very marginally lower (economy mostly) than using 6 drivers on a 6 cylinder engine. It certainly wouldn't put me off, if the price was right.

Hope that helps

I have used both computer and have found the M4 a fantastic computer for street use, (used on a Mitsubishi GTO) but have also found the Power FC to be brilliant for a street driven nissan.

I think in the long run the PFC being plug and play will be the cheaper option as the options on the Motec are quite expensive

To get the Motec upto a decent level of tune, it'll cost a packet load as you start with nothing

Nothing wrong with a PowerFC, its one of the best ECU's for the cash considering you get all sorta extras that save time with tuning.

I have a R34 GTT Power-fc with boost control kit and hand control, perfect working condition, $1300 firm.

was going to use in Stagea, decided to do a basic chip remap and keep using piggybacks.

As above, the MOTEC has more features and is (on paper) the superior ECU. But it depends what you will use the car for, if if you can justify the extra (purchase/install/tuning) costs of the M4. Which will be significantly more than the PFC.

I would go PFC simply because unless your car is track orientated you wont know the differnce, and the extra cost is not worth the 'i run a motec' bragging rights.

I'd go Apexi pfc simply because

Plug and play - no cutting into loom so its good for EPA or if you are putting the car back to stock for whatever reason

Cheaper to buy - usually always a demand if you want to resell plus they aren't being made anymore so the more rare they get the more they will be worth in some sense

Cheaper to tune - over-all you will save on buying the ECU it self then the tuning as well plus on installation which the MOTEC will need for sure

More tuners available - I don't believe a lot of work shops can install and tune motec

Does the same shit in the end, not like its a full race car

Plus Apexi PFC is proven to work well on skylines, theres millions of people running one :yes:

Motec ECU can plug in like the PowerFC but needs a custom adaptor loom

that has the correct plug for engine loom on one end and plug for Motec

ECU on the other end.

The good part about Motec ECU is it can fit in any car with the right

adaptor loom.

PowerFC is more of a one engine only type of ECU unless adapted to fit

on other motors like R32 RB26 PowerFC on a R32 RB20.

Also I think Motec ECU has higher resolution maps which helps with fine

tuning the shape of the power graph and extra features like what

everyone else has already said.

Motec ECU can be used on a Methonal or Nitro engine.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
