if u dont mind spending the coin noel, go the haltech. also the boost controller is only $120 for it

P.S only downside is for the 33 u gotta get it wired in

Can the haltech not only detect but also manage knock.

[Devils_Advocate21]

I thought there were ecu adaptors for the haltecs for the skylines??

See what i mean, theres another partial answer marc. Knock sensor. good to have. Knock control, better to have. What else, dual mapping, timing, spark, air fuel, Just what should a good puda have and be able to do with what it has.

I'm not as familiar with the Haltech but I'll answer where I can.

Dual mapping: PFC - no. Haltech - I think so

Timing/spark, fuel maps: Both are full replacement ECUs so have full control over your fuel and ignition maps

Airflow meter: Haltech allows you to get rid of it by replacing with a MAP sensor. PFC forces you to keep an AFM of some sort, though it allows you to choose between maps for some of the more common swaps (Z32, Q45 etc). You can go the D-Jetro version which lets you go AFM-less but to be honest, unless you're running stupid amounts of horsepower or ridiculously big cams - keep the AFM. They're better at measuring the air and you'll end up with a cleaner, more fuel efficient, nicer ride at the expense of a tiny bit of throttle response at the top end.

Read my last post Matty. i have been around hot cars long enough to know that my mods probably wont stop at that. The puda is an item i only want to buy once.

Unless you're aiming for more than 500hp I would stick with a PFC....the things I mentioned above are just a quick summary of its features from what I remember.....

Saving the money through it pluggin into the standard loom is also a large plus!!

Another thing to consider Noel is whether you want to stick with your air flow meter (MAF) or use a Manifold air Pressure (MAP) sensor.

Haltech do make a plugin ECU for the R33, the one I've seen in the E11v2.

In my understanding, the Haltech does retard timing when it detects pinging, which is great. That was pretty much the only thing that I wanted in the PFC that it didn't have.

[Devils_Advocate21]

anything above the 300-350 rwkws will cost alot more to achieve

[Devils_Advocate21]

Not only is that with knock a reliable tune can also lessen the chance of exeeding high knock counts? Bringing tuning into the equation

I made 307rwkW with a PFC without a problem, which would have easily been > 500hp at the crank. Basically, as long as it's capable of running the injectors/coils and recognising the sensors you have, you can make as much power as you want. I dunno how big you can go in the injectors with either ECU before it can't run them quickly enough to fuel properly at idle but I certainly didn't have a problem with it.

The Maf sensor tend to be a bit lightweight as far as reliability, and is one reason I went with a microtech

i believe the haltech has a wider tuning map, 32x32 i think. also there is built in rev limiter, launch control, nos tunability, its a hell of a lot newer, will be updated as the program/software/hardware progress. it also has a data logging feature. u can purcahse a digital dash for $1600 which shows all ur telementory (sp)

i sold my PFC as soon as i realised how good the haltech was

heres the long term deal matt.

current mods (stage one)

fmic, pod filter, turbo back exhaust with hiflow cat, 10 lb boost.

Next stage,

Hiflow turbo, in tank fuel pump, fuel reg, 550 cc injectors, boost control

Stage 3

Stage one cams, Adjust cam gear. Aftermarket plenum.

Stage 4.

forged arse end.

Stage 5. Headwork. titanium valves, stiffer springs. Possibly solid lifters. mild port and polish with manifold match up.

last stage. turbo upgrade.

that is where i will eventually take it. I aim to do it in stages to keep it interesting.

Yeah the biggest killer of them afaik is backfiring. The wire is pretty thin and it just breaks. That said, I replaced mine once in the whole time I owned my car, and that was to swap in a bigger one

There's no denying the Haltech does a lot more, it just depends on whether you can justify the extra expense. I was more than happy with my PFC though, the results were more than acceptable and cost a lot less than a Haltech, particularly given that, at the time, the only other available plugin was the Wolf3D which I felt didn't suit my needs.

The moment you want to start looking at logging or telemetry , you'll need a Haltech/Motec/Autronic etc

As far as extra expense goes marc. what is the better deal. A used pfc that is commanding ridiculous money for reasons that escape me or about another 400 bucks for the better computer with back up available.

[Revhead]

I haven't looked at PFC prices lately but they've recently gone out of production, which would likely be pushing up the prices.

Putting myself in your shoes, I'd go the Haltech. It'll do more, you can guarantee it'll expand to suit whatever you do to the car later, there's a plugin version available now so you don't have to cut the loom... and, if the prices are getting pretty similar now, there's no reason not to go for the technically better option, and one that has manufacturer support for the forseeable future.

Doooo eeeeeet

[shanef]

noel jump on the phone to the ogar (dan ) and get a price for a haltech and a pfc and get his opinion

My thoughts excactly marc. What i was tyrying to find out tho is, are there any other worthwhile options out there, Link, Wolf etc.

[shanef]

oh and while ur talking to him, tell him im still waiting for that turbo farken

Opinions are like arseholes shane, everyone has one. I could ask Col, (already making big powah, or sid kid. guru. and gaed knows how many others and come away with different answers. It aint like injectors or a fuel pump. there is so much dark science to these bloody pudas.

[Revhead]

Unless they've changed a lot in the last 18 months or so, both Link and Wolf (and Microtech etc) tend to be racing ECUs - they will get your car running, but lack some of the things that make a car nice to drive day-to-day. Things like cold start, idle control (when the aircon cuts in, in particular), variable cam timing control etc, and they generally have a lower mapping resolution too.
