Just looking for people's opinion's on the latest microtech, whether you use it or not? I know the old ones didn't use a closed loop so they were pretty bad on fuel and were bad on cold starts but i'm told by my mate that the new L series of microtech's now use a closed loop and are much more programmable etc.

He can get me the LTx12 and it will be going on my Rb20 then onto my Rb30DET. The main reason he wants me to get it is because he is mates with the South Australian distributor and can get me it at a very good price!

I have been looking at the power fc but if they really have improved i think i will get one because he can get it cheaper than a power fc!

If you have a Nissan then definetly spend the extra money on a Power FC. Apart from Autronic (without breaking the bank) they are the greatest ECU for a Nissan, Microtech have made slight improvements but not enoguh to better the Power FC.

definatel microtech most of the top cars use them

im definately happy with mine

i have also supplied and fitted 7 microtechs with no problems

mmmmmmmmm 2 very opposing opinions, this is going to make my decision very hard. so is your fuel economy pretty good compared to the standard ecu? and how are cold starts etc? if you can tell me any things that make the microtech more appealing over the power fc please tell me!

On an oooold microtech of mine the cold start was perfect. This is the hardest part of tuning an aftermarket ECU as you only get one shot at it every day and it could get costly. The advantage of the PFC is that it retains the same factory settings for cold start etc and that makes tuning alot easier.

It's been said a number of times, but I'll reiterate: an ECU is only as good as it's tuner.

You know the best way to chose an ECU?

Find a tuner that you trust, and ask them. If you find a tuner and go, tune this, and they have never used it before, they will obviously give it a go, but it probably wont be as good. And you have to trust the tuner, its a bit like a doctor, you wouldnt go back if he gave you panadol and a slap on the back if you broke your hip in 3 places.

Thats what I think anyway. Also it seems most people are using the PFC as its a plug and play pretty much, from memory wolf, haltech, etc all do plug in's now too.

I have the LT12 in my R33 and wouldnt go back. The reason I chose this one is my tuner reccommended it and knows them really well. I get 9-10km per litre but the cold start was a little bit hard to get right at first, but an air temp sensor sorted that, now its good. Its much of a muchness find a good tuner and ask what he wants to tune.

ye its a 32 so the cheapest i've found it $1380 and the microtech i can get is $1000 and both come with a hand controller. i think i will go the power fc becuse the tuner i want to use prefers power fc's!

I have a lt12s microtech in my R33 gtst and i am extremely happy with mine.......they actually cost more than the power fc's and make more power....

The power fc's still use the afm where as the lt12s dont use one at all...it is replaced with a bit of fabricated piping, so is less restrictive.

It also has more tuneability than a power fc.

I gained 50rwkw from installing the microtech but knowing a good tuner that knows microtechs helps. My car had 160 rwkw and after installing the microtech i got 209.1rwkw at 12psi with the stock turbo!!!

I have no problems with coldstarts as i had an air sensor installed at the same time.

I know a guy that installed a power fc in his R33 gtst and has got a high flowed turbo and only has 211 rwkw at 15psi and before he had about 180rwkw...... a gain of only 31rwkw.

The extra money for the microtech is definatly worth it..

Hahahaha....

That is one of the more stupid things I've heard. I'm not sure if you are serious or are an aspiring stand-up comic genius!

You'd be good at the latter.

Mate, ECU's do NOT make power. The tuning of an ECU does that. If you have say, 2 x 200HP cars. Both identical. If you install a Microtech to one and a P-FC to the other, neither will make more power than each other. I'm sure good P-FC tuners will be able to tune an ECU to make the same power as a similiar car with a Microtech. Also, you may of had such a large gain, but the person you stated that only had the 31rwkw gain with the P-FC probably got much better economy and ran a safer tune.

I would go the P-FC, simply because most tuners are more familiar with them when it comes to Nissan performance cars. Another advantage of the P-FC is the knock sensor, could come in handy one day, y'know...

Anyway, I hope you make a good choice, no matter what ECU you choose. Good luck

Im glad you find it so funny!!!

My car is absoulutly fine, never had problem with it and i dont find it any less economical than before the install of the microtech.....and yes it obviously produces more power as i found a very good microtech tuner.....

Its just my opinion as every one is entilted to one...and i do think that microtechs are definatly better than a pfc...

To RB MAN

If your in Brissy i know of a good microtech tuner and he isnt as expensive as most tuners.....pm me for details if your interested..

Another vote for going with the tuners choice.

My tuner (P.I.T.S) said PowerFC or Wolf3d. I tried the Wolf and am extrememly happy as the tune is perfect. Everyone who's been in my car has commented on how well it runs for a moderately modded Skyline. Since the tune and running 16psi I have never heard it backfire at all or splutter even once at high revs. This however, is due to a good tune, not a good chip. I'm sure I would have had the same results with a PowerFC.

It's all about the tune!

I hear what you are saying, but its not really true....is it??

The quality of the ignition and injector drivers surely make a difference. My old Microtech wasnt too strong in the ignition driver dept, as the thing would go up and down dependent on the load on the electrical system etc, headlights. wipers etc Also the processor speed with repsect to injectors etc surely makes a difference.

In the wash up it may not be a lot of difference, but i would be surprised if you put two ECUs on the same modded car, that they both would be able to handle the same amount ignition and boost and power wihtout having to wind fuel in and ignition out. Also certain ECUs can surely be tuned closer to the brink of detonation as they have finer control and control loops/channels etc

... I think. i repeat, think...im not saying you are wrong....but thats a few things i considered when looking at ECUs

I got the same gains as you with an safc11 so have alot of other people, should we be claiming the safc is the superior managment??

      R35 GT-R production ends after 18 years

      By Rezz · Posted

      Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R.

      Thanks. We getting some parts along too so he will be solving the speed issue like next week so i will let you know what he came up with.

      R34 25GT Engine Light 21

      By MBS206 · Posted

      21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.

      By CF.Panda · Posted

      Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.

      RB25DE NEO with Haltech ECU

      By MBS206 · Posted

      Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
