I currently have a R33 S1, GTS-T, a couple of minor mods, 10psi of a MBC, r34-GTT side mount intercooler, exhaust and intake.... keep in mind this car is an everyday driver....

im happy with the current power it makes. It is however running a stock ecu with 10psi.....therefore you see a big black smoke exiting the exhaust if i give it some stick....

I have a friend who is selling me an haltech interceptor ECU.....my question is, is it worth the conversion??... what will i gain from it?....drivability?...more power?? smoother power?? ...better fuel consumption?....what is the most noticeable improvement i will gain from an aftermarket ecu??

Because once i have bought the ECU, i have to take it for a tune as well.....which is $400-$500.....

Has anybody tried the haltech interceptor??....

who is the best place to tune if i do decide to get it??...

I can tell you lots of reasons why not to do this...

First of all it's not a full ECU. Just a piggyback. So you are still running from ur stock ECU

oh !! man where to begin ????

ok.. here's my story,

I bought the Interceptor about 2 years ago and it costs 300-400 just for wring it.

took it to 3 different tuners still nothing but disappointment..

It can't control boots cut, MAF cant be clamped

I'm only running 10psi. I even called up Haltech and they admitted that interceptor may not work on R33 well. (something like Interceptor can't get R33 triggers correct )..

Anyways if 3 different tuners can't get it right it has to be the unit...

Man ... get a full ecu or even SAFC or Emanage will do a better job than this.

but hey I'm not anti-Haltech, their full ECUs (e11) are very good units if you can afford..

There are soooooo many options out there for R33s... and as far as I know and from my very expensive experience Inerceptor is not one of them

it's worse driverbility, more fuel consumption etc ..etc...

Ninja, i think you need to find a good tuner, many have had good results with the minor mods you have. Another ecu you may wish to consider for a smaller budget is an emanage ultimate. Both are heaps better than a safc. Having said that look up the thread in the stagea section about the Jaycar fuel trimmer, ive had good results for up to 200rwkw with the stock ecu.

Sounds like the haltech interceptor is more trouble then its worth................. sounds like its cheaper and more reliable leaving the stock ECU in there.....correct??

Finding a tuner to do it right could be a problem....from the sounds of thing....i was going to get c&v performance in carringbah to do it....but not after the senninigans that you guys mentioned....might rethink my option

Ninja 09 what negative result did you experience from it??

basically, you should be able to clamp the MAF at 5V using the interceptor so that the stock ECU would not boost cut, Tuners say that it's impossible to do this using interceptor.. so through out the rev range (in any gear), 3k, 4.5k, or even 5.5k it boost cuts..there were so many other issues tuners mentioned but I don't know how to explain. First I thought it's a tuner problem and kept changing the tuner.. and after 3 top rated tuning shops, Im convinced this unit is not for my car...(I learned the expensive way)

Same time had a friend using an interceptor in his Supra (uses a MAP sensor) worked perfectly running well over 300rwhp

I got 266rwhp at the moment where my turbo could easily push over 300... But I'm getting the stock ECU remapped. hopefully remap will work fine and I can use the interceptor on top of that if I have to..

Have you considered ECU remap or Nistune?? both these are cheaper options .. If you are not planning any further mods in the futuer, remap is ideal.

Ok, a interceptor will work perfectly in any model skyline from R32,33,34. Yes it does clamp the boost cut signals and yes it will control the fuel and timing by intercepting the original signals going to the factory ecu. It will even control the factory boost control solenoid. In the case of a supra for example you can even use the interceptor to clamp the signal to the speed cut and do away with the extra cost of purchasing a speed cut defender.

There is not one company in WA that has been satisfied with the Emanage unit which is actually just a piggy back unit the same as a Haltech. 90% of all problems relate to the installer and the tuner.

I 'm surprised that Haltech would ever say that they cant support an interceptor on a R33. just check there web site and you will see a base map for an interceptor there to suit R33.

A PowerFC is a good cheaper alternative to a stand alone ecu but I believe that the interceptor will suit the application of minor mods a lot better.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
