Hey people,

Put an RB25 with a few mods in my R32 & am currently trying to decide what sort of aftermarket ECU setup I want to go with.

Have been considering a Nistune, etc remap of standard ECU, Power FC or something like Haltech.

Just after some opinions on the pros & cons of both AFM & MAP sensor based ECUs.

I know AFMs can suffer stalling, etc due to reversion of air when throttle is suddenly shut but a BOV should solve most of this, yeah?

Also, obviously with a MAP sensor, you do not need to purchase upgraded AFMs...

So while the Haltech is more expensive than the other options, by the time I buy a Z32 AFM & EBC (which the Haltech also has) I will be getting close to spending the same money. I just dont know heaps about MAP sensor based tuning...

Did your tuner give you a short list of ECU's to choose from, or recommend one more than the others that he prefers to use?

Im selling a cheap MAP-ECU at the moment

(shameless plug)

going Power-fc instead for my track-RB26

www.map-ecu.com

in my Rb25 I am using an AEM F/IC-8, like a greddy emanage, but runs off manifold pressure not air flow meters

seeing 225awkw / 240rwkw at 14psi

with a 18psi actuator Im hoping for around 250kw at the wheels

lap-top tuneable

Havent really decided on a tuner yet. So far have done all work to car myself however this I obviously cant. Took my car to a shop recently for some diagnostic work & he suggested Haltech & strongly suggested I stay away from Nistune.

The other advantage to the Haltech is a friend of a friend used to work installing & tuning Wolf's & now deals with Haltech so can possibly get a very good price.

However, saying that, Im still quite open to any ECU, then will find someone to tune it.

Have just been looking at Link...

Why do you ask? Do you have any other suggestions for ECU choice?

haltech,autronic, are the main stream ones id look into. all around 2k.

ems,vipec,link,adaptronic,wolf. "can" be just as good but due to there low usage tuning can be abit hard to find.

microtech is good but from past experiances on there older models tuning resolution is abit poor. not sure on there newer "LT" models

motec is very good, but unless its a top of the line m800 etc etc tuning software is still dos based and the fact you have to "buy" options for them ontop of there already high price is abit of a turn off.

my pic of the bunch is autronic. very reliable and easy to tune. (ie: low cost of tuning)

id steer clear of a maf only ecu. (i say maf only because most of the above ecus can run a maf sensor aswell,) makes plumning easier and a map sensor is far better than a 20 year old air flow meter that maxes out and then is tuned by a good guess..

power fc is a great choice for plug and play, but autronic and haltech and motec do plug ecus. either in the stock case or use a patch loom.

cheeres.

Pick your Tuner 1st. Haltech Platinum is as good as it gets for full aftermarket but the MAF Option is not yet functional.

Any tuner that cant see the benefits of Nistune on a road car should be avoided.

Yesterday we gave up on a wild GTR with PFC that gave nothing but trouble to 1/2 of WAs tuners and fitted a Nistune, Problem solved.

Not another one of these threads... :)

There have been similar debates in the past.

If someone is telling you to stay away from Nistune - in all honesty - i would be questioning why they would say that and if they actually have enough of an idea about products to say that.

Cost vs gain, Nistune is the best bang for buck for mild/medium street cars and uses everything required for a car to run factory with a better tune (ie cold start, idle return, under load with A/C on etc etc).

Nistune is also a piece of piss to tune, very cheap tuning costs as its very simple, Nissan has done everything for you remember, you're just adjusting a few table/settings as opposed to a Haltech for example where you have to do the entire thing from scratch which means a big $$$ bill for a FULL Tuned ECU to the level that Nistune would offer.

I've never had issues with any of my AFM cars - except where i replaced a dead AFM with two 2nd hand ones.

Both started playing up a few weeks later, intermittent and took a few weeks to sus out. That way my own fault though :)

ok. As I say I was leaning toward Nistune but this guy sorta put me off. Reckons there are still too many glitches at the moment & I had heard stuff about TPS problems, etc but from recent searches these seem solved...

My other concern is, as some of you may know, I have recently written many threads about my car overfueling on idle.

My injector pulse is 7ms & AFM signal is around 2v.

This guy & another well known tuiner have told me its due to too many mods for standard ECU, playing havoc with airflow.

It sounds like Nistune leaves the idle setup very standard so will this fix my problem?

I assume fuel maps, etc at idle CAN be played with if necessary?

cheers for the opinions so far guys

    • I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.
    • Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.
    • Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.
    • It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!
    • Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
