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.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
