Hi Guys,

My new turbo is going to into my R34 GTT soon and so a retune is in order

After a talk with my mechanic and him talking to Insight, my car is due to go on the dyno in 2-3 weeks

I just wanted to see if anyone else has had their car tuned there and what was your experience with them?

How was the staff? How did your car run afterwards?

Thanks in advanced

I and a couple of other members on NSCC have had there cars tuned by Scott at Insight. He did an awsome job on my car and sorted a few issues that were not picked up by my previous tuner.

His Dyno cell is a work of art in technology.

You will be pleased with the result

So the car got dropped off on tuesday morning and I picked it up around midday wednesday after the cold start tune

Car made 220kw on 16psi, Maxed injectors and AFM

I am loving the car, a lot more low end torque, boost is holding throughout the revs.

They also fixed an idling issue I was also having.

The guys at Insight were great to talk to, had a lengthly discussion on options for the car down the track

I am very pleased with the outcome

Just that the injectors and AFM were maxed.

Ill put 1000cc injectors and I'll need to change the ECU, thinking Haltech

Also a problem with the VCT which ill make sure is fixed before the next tune

Had to weld a new bracket for the wastegate as the one on the turbo wasnt strong enough to hold boost

That seems ridiculously laggy for the power output, GTRS especially. Did they say you had to address anything after the tune?

There are afew possible reasons that could have caused this, that R.o.B. hasn't mentioned, in terms of the extent of modifications........

As an engine builder myself, having the right tune for start up (Standard - Standard Factory tune is sufficient.......Modified with Nistune or aftermarket ECU - for anything out of the norm, besides a test start up,dyno is recommended!) after a rebuild is critical. A handful of engine rebuilders I know (which includes touring car/race car engineers) will only warrant (high performance street) engines tuned by Scott at Insight Motorsport!

As a racer for years, both drag & rally, Scott's tuned some of the best. I've pulled up at his workshop & heard something on the dyno before I get out of my car, only to find Scott tuning something like Glenn Seton's old Peter Jackson Ford Sierra RS500 Touring car or 500kwatw F2 procharged street car!

My only advice, as an engine builder, is preparation. Plan - talk to everyone! Find reputable engine builders & tuners. Talk to them, tell them what YOU want to do, examine the pros & cons. Collect parts that are going to work for what you want, then start letting the spanners fly. Don't deviate from what you want your car to do (bigger numbers coming on at 6500rpm are not as good as slightly lower numbers at 4500rpm - depending on the application).That way,when tuning comes around, you won't be disappointed by a mismatch in parts.......

Ok, so your intake hasn't been greatly increased by a HUGE front mount. Are your cam sprockets standard? Is your intake manifold standard? How well does the Power FC handle the operation of them both?

Sprockets and intake manifold are standard

Is your PFC causing this or is it an oil issue? The oil passages around there are pretty fine,make sure they aren't blocked. For a standard setup, when you hit 4000rpm, the engine should pull hard!

I ah, *AHEM* hate missing stuff, but yor PFC might be causing you issues.

My first question is, who tuned your car at Insight?

POSSIBLY, there could be timing issues that could hamper the operation of the VCT or manifold operation? Please, anyone, correct me if I'm wrong! How many km has your engine done? When was the timing belt changed, was it correctly fitted (as to cancel out a mismatch between crank & 120 degree reference 1 & 2 - 1 tooth advanced could make a difference!)?

Unsure, my mechanic hasnt had a chance to have a look at the VCT since the tune

I'll mention this to him though

Either Scott or Bob would of tuned it.

Engine has done early 150k from memory

Timing belt was replaced before I got the car (April last year)

      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.
