Lol...

Cross weight is for getting left and right turning the same (use front left and right rear to get %). It's used to jack coil overs to equal cross.

to get rear need just find the difference of 100%.

58.4% FRONT

41.6% REAR

You guys are funny!

And I just though about the boost...probably some nitwit cut those wire in the harness somewhere to install boost control in past. I'm about to go run new ones straight from ecu

What was wrong with boost? Solenoid not controlling properly?

Haltech wouldn't controI because it wasn't getting the boost solenoid wiring back to it. just finished running wires from ecu though. Apparently someone cut the wires to install an ebc because the wires to the solenoid did not get signal back to ecu pins. It's all good now though. Made use of one of those MAF wires I wasn't using ;) repinned ecu wire 27 (Front MAF signal) to 25 (Boost control solenoid ground) and then used the MAF 12v switched as a supply for the solenoid...I'm sure it will work now.

Going to try to get base duty dialed in for 10 and 12 psi then tweak closed boost mode from there. Based on my tests the other night I should be up in the 18-20 psi range even on medium actuator if the solenoid is up for bleeding the boost. But I'm bringing tools to tighten the arm in case.

As fast as this car is at 10 I can't wait for 20!

Fyi the EFR solenoid is marked + and - in the plastic. You run 12v to the + and the ecu grounds the - on a pulsed duty cycle to bleed. Closed loop actually starts at your set duty cycle then adjusts to actual boost. Basically I never had it wired up.

VERY close!

3175 lbs --> 1440 kg

58.4% front

49.7% cross weight.

Is that full weight or with stuff stripped out, and are there side impact bars, being an early model perhaps not?

I thought it would have been in the 1500's range for sure...

Full weight. No jack, spare, floormats, or stereo (but speakers are in doors). AC PS and all still 100% on car.

Just got done with tuning session one and went out to enjoy the car. I will need efr high pressure wastegate because I couldn't get stable boost on top end (dropped to 16.5 psi) so I was stuck with only 464 rwhp. But oh my goodness does this car just own all driving it around. What an INCREDIBLE car and incredible powerband. I didn't have time to get timing and all right because I was fighting with boost so much.

The red graph one finally had boost flattened out in the dip but knocked a touch in the top. Again no timing changed off of haltech base map yet.

10 psi was 375 whp.

Again missing boost threshold

Heres my data.

First tune, ran out of dyno time. Fought boost control for a long time then just went to open loop on Haltech. I should have played with that more before dynoing. Boost on graph is PSI * 10 (for scaling purposes) and is straight from the log. It literally rained while we dyno'd so 100% humidity and 83 deg F ambient.

This is STOCK Haltech timing advance (untouched). Only would knock at 20 psi at 4400 rpms during spike. I'm DEFINITELY losing boost response on this because the logs with the wastegate hose pulled are showing 21 psi at 4100 rpms (as opposed to my lazy 4400 that was kinda of spiking at first).

Anyway, pumpgas 93 (with the 10% ethanol they have in my area).

2.75L BC stroker

New N1 block 86mm bores

tomei poncam A

6boost manifold - divided for IWG EFR

8374 EFR .92 IWG divided

ported head

SS +.5mm valves

squish pads removed

Hypertune V2

stock intercooler

I WILL be ordering the high boost cannister and getting boost leveled out at 16-17 psi for base and using closed loop for tuning. CAR IS AN ABSOLUTE ANIMAL!!!

I bet it has 130 mph in it right now!

Also it should be noted on STOCK intercooler I'm seeing 115 deg F when hammering through the gears (all the way through 4th) on the highway. It was AT LEAST 125 on the dyno every pull. Air temps drop drastically when on it...ironically they increase while you cruise (or sit in traffic). Makes sense as all that is moving is IDLE air. But under load at 18 psi and this power level the stock intercooler is keeping up well so far. Temps pretty much drop the whole time you are in boost. NICE EFFICIENT TURBO HELPS I AM SURE!!

Not much to update. Busy doing other things today.

I did, however, take an hour to make a heat shield for the turbine housing. I wanted to protect my powdercoating.

    • 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
    • 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.
