Just a few cents...
Been using All Star since I purchased my Skyline (3-4yrs) and was recommended by them to install a Haltech. Must admit, should of keep the pennys and moved up to a Motec but hey we all can't get what we want all the time.
My car has been in for the last 6 months.. well I didn't need it as the missus had a work car but now she's changed jobs.. Anyways I have always had some minor issues with cold starts because the Haltech doesn't have a AFM, I have found a few stabs of the accelerator before starting and a couple once you've kicked it over will help. I had the same problems of stalling and idle bump all over the place.. Currently each morning I'll do what I just said and its fine and idles around 1000rpm.
My current problem is my Haltech is old now E6H and finding after my latest update.. Port and Polish, new manifold and sending the ECU back to Haltech so the get them to rectify the communications module for the laptop not working. The car will rev to 5500 without a hitch, once it hits 5500 the haltech ignition module voltage drops from 12v to 3.2v. Haltech no longer support my model ecu but Richard was good enough to get on the net and found US Drag Cars using the same model had the same problems and are using a simple resistor kit to get it fixed. Richard is an exceptional mechanic and when it comes to electronics and cars he is right up there. Think he has an electronic engineering degree, from memory.
Currently the car is set up as follows:
Stock Engine with port and polished headwork (just done, so unsure of additional benefit until put back on dyno)
ARE Intercooler with 2.5" Piping
Stock Turbo Hi Flowed 2 yrs ago, still looks and feels great, will hold 22-24 psi no prob, only using 15psi approx (need a ECB)
3.5" Dump to Tip Apexi N1 Exhaust, CAT only and one Dog/Muff at the tip.
Haltech E6H with Haltech Ignition Modules
750cc Nismo Injectors - should of only done 555cc Richo reckoned.. I source these from Nengun myself.
700hp in tank fuel pump with Sard Rising Reg.
Monsta Performance Manifold, however Richard believe the stock one is just as good. - Had to try ebay for something besides accessories
All else stock.. maybe a upgrade clutch supplied by All Star...
Richos last dyno before the port and polish was 240rwkw with 1100nm torque.
Also, I have found many other tuners send there work to All Star when they can't get it working either..
Hopefully after Thursday Richo will have my car running smooth and getting closer to that 300rwkw that I wanted to achieve when I first go the car.
Peace out...
P.S haven't found another tuner and the one I did have a chat to has moved (predetor Motorsports) whom where just down the road from Bob Romano.. who mind you is way way more exspensive.. $597 for a Service with no Dyno... All Star $300 with an Hours Dyno approx..
