I am looking for aftermarket ECU for my GTR, and I don't have any knowledge in tunning or setting ECUs, but some people mentioned MoTec makes the best ECUs in the market?

Can anyone give me advice for MoTec ECU system and their approximate price as well. Regards

I have Motec M48Pro with all the fruit (wide band control, data logging, etc) and as already said Motec is probably the best of the aftermarket ECU's, with Autronic running a close second, IMHO. Mine is not used on a GTR tho.

Motec is not cheap, although I haven't checked their prices for a few years. One of the reasons Motec isn't cheap is that they charge for things the others include in the price. For example the price they give for the Motec model you buy is just that.....the price for the ECU. If you want a loom that's extra $$, sensors same. Then if you want wide band control you have to pay extra for that, etc, etc (all Motec ECU's have the full range of capabilities/options built-in, but to access them you have to pay the Motec fee and then they turn the option on by entering a code. It can end up adding up to many $$$, but there's no doubt about the quality.

Depending on what your planning to do, you might be better to look at a PFC, which is essentially plug-in and go, but if you need a Motec there's no doubt it'll do the job.

Not quite following you here.....you'll still need someone to tune the M600.

Not with the logging and wideband option. Its quite easy to do yourself with the motec Pro tuning option.

MoTeC have whats called a quick lambda function in their ECU's, It lets you create a map the holds your target lambda value, and essentially you drive the car, get someone to press the Q key on your laptop and the ECU will tune itself to the target air-fuel mix.

SydneyKid once tuned a mazda race car completely in 2 laps of bathurst using this setup.. Very cool stuff.

I know what quick lambda is - I've been using Motec for years. I'm not particularly interested in what someone did with a race car on a race track, it's a totally different thing to tuning a road car essentially from scratch on the road. Even Motec themselves recommend tuning the vehicle on a dyno and then fine tuning on the road.

thast exaclty why MattSR :D... of course it will need tweaks on installation but essentialy MattSR your were spot on with how my motec will run .. i have the money to do it now just gathering information and the right man to do it ....

Seems like a an expensive way to get rid of a topend miss and gather some more clean HP but it sure beats interviewing each mechanic thats guessing in my area .... A progressive upgrade for the gtr ......cant wait !

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
