Hey Dave, I noticed you had a bit of a boost spike there early that almost hit 20psi.

Also tuned on a ramp rate of 200 which is good for numbers but how about real life on the street ie. pushing it hard uphill?

Jeff at Speedlab runs ramp rates of about 150 which may show around 10kw less on the print out but much safer on the street.

Just keep an eye on the detonation bud.

That being the case....my guess of 330 to 340 wasn't too far off.........sorry Darren, you may have to share that prize with me :thumbsup:

Yeah I saw that. I was checking it against my old dyno sheets when the HKS EVC was working. The sheets below go from right (oldest) to left (just prior to blowing engine)

The same early spike and then drop off occurs on the low boost setting on an earlier dyno run as well. You can see it on the second sheet below dated 12.4.06. The high boost (blue line) is set at 17psi and trails off to 16psi where as the low boost setting (red line) spikes initially to 12psi and then drops off to 9psi. Interesting.

might pay to take your car to a different tuner just for a check up as martin is known for making grenades.

just be carefull is what im saying.

the run isnt in shoot 6f and some of the other settings look a little funny so just be aware that his not as good as he thinks he is.

at the end of the day he doesnt have to pay for your motor so what does he care.

also that boost spike is a concern.

Yeah I think Martin is probably one of the best tuners in the country but his biggest issue from what I'm hearing from many that have seen him recently is that he doesn't spend enough time on the tune (unless you know him well).

I'm not inferring that this is what Martin does but in general it's not good enough to do a run on the dyno then go back and tune only the ghost part of the map, you need to tune the whole map (fuel & timing) because on the street the load and temperatures vary which will always put you into a different part of the maps.

Have a look at the ramp rate that Shaun at Boostworks ran on Sat (150), figures may not look as high as some people would've liked but at least his ramp rate equates to real life on the street moreso than a rate of 200.

Just because your car doesn't detonate on the dyno does not mean it won't on the street.

David... nice numbers there for sure.... I would suggest if you want another tune to see John Keen at Southern Hi-Tech dyno. He does good work.

Enjoy your newfound power mate!

Good advice from sled and the boys above too.... the last thing you want after the long wait is a grenade resulting in another one!!!

Another thing I liked about Shaun at Boostworks was that he monitored temperature, timing (detonation) and fuel supply very closely on every run.

Proof of that was that with some cars he immediately back off when it leaned out or started to detonate.

I've stood next to my car with one tuner just north east of town who revved the crap out of my car then said, gee I got abit of pinging there :) WELL WHY DID YOU CONTINUE TO REV IT THEN!!! and sometimes 2 or 3 times after he realized that it was either detonating or running out of fuel.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I had absolutely no symptoms whatsoever that anything was wrong.... I'm very happy it was all spotto'd and re-bled and re-torqued and aligned though. Will be picking it up tomorrow and undoubtedly be like "Oh, that clunk is gone" "Oh, the car really wants to drive straight" "Oh, that pedal feels better" "Oh, it feels like I've gained 25hp" "Oh, the handbrake works now" It should have been a sign that the new Project Mu shoes had 3mm of pad depth on them out of the box, and the OEM ones from 25 years ago that we took out also had 3mm of pad depth, implying the issue was not, and never was the shoes, but we put that down to it not being adjusted correctly. It wasn't, but it wasn't even adjustable at all given one side was boned and the T Junction of the cables was on a 45 degree angle, the non-working side being the one on the massive angle. Obviously when I had adjusted it and reset it and re-tensioned it I had either got it stuck or something along those lines. Oh well. Live and learn and absolutely could have been catastrophically worse so I'm rationalizing it as a win, kinda. I also got the chance to measure the distance between rear rim and the suspension arm/shocks and found a 30mm rubber block only just doesn't fit there. Which is great to know before ordering wheels, when I assumed 30mm was easy. The man with the Porsche adapters has rims that use 23.9mm of that space, so it's safe to assume I have between 23.9 and 29.9mm of space there to play with on the inside. The wheels looked pretty stupidly pokey with the 20mm spacers on the rear, only for me to find that the studs come out another 12mm and the wheel doesn't actually sit flush with the hub because you're supposed to cut your original studs. The wheels do have cutouts that kinda accomodate it, but not fully. So my 20mm spacer was anywhere between 25mm and 35mm. ~25mm and send it will determine on where the wheels sit with the spacers on. When I put the pads in for the track day I will mess around with spacers (with wheels that do not clear studs properly when mounted to spacers) and do more math, for the last time, for the 7th time.

      Lucky pick up Best to find these things before something horrible happened to the yoke flange thingies I would hate to think what would happen if it dropped the tailshaft  Hopefully the holes are not flogged out in the yokes and it was just the bolts that got munted  As for the hand brake.....ouch, look like the disc got rather hot, and I assume smokey, I recall when I had a front caliper seize on the Commodore, there was lots of smoke and the disc was glowing cherry red when I was able to eventually stop and have a look, and stopping a big heavy car, going down a big hill with some rather high RPM down shifts and some hand brake action is something that makes you think hard about life

      One of the things that never seemed right was the handbrake. Put in some nice new Project Mu shoes. We figured the rears were out, so why not. We're right there. My handbrake never worked well anyway. Well, this is them, 15km later. 67fdcf94-9763-4522-97a4-8f04b2ad0826.mp4 Keen eyes would note the difference in this picture too:   And this picture: Also, this was my Tailshaft bolts: 4ad3c7dd-51d0-4577-8e72-ba8bc82f6e87.mp4 It turns out my suspicions that one side of the handbrake cable was stretched all along were pretty accurate, as was my intuition that I didn't want to drop the tailshaft to swap them on jack stands and wasn't entirely sure about bolt torque. I have since bought the handbrake cables which have gone in. I'm very glad that I went to my mechanic friend who owns an alignment machine to get an alignment before the track day, because his eyes spotted these various levels of "WHAT THE f**k IS GOING ON HERE?". Turns out the alignment wasn't that bad, considering we changed the adjustable castor arms out for un-adjustable castor arms, and messed with the heights. Car drove pretty good with one side of the handbrake stuck on, unbleedable rear brakes, alignment screwy, and the tailshaft about to go flying and generally being a death trap waiting to happen! (I did have covid) (I maintain I adjusted the handbrake correctly, but movement caused shennanigans and/or I dislodged the spring on the problem side somewhat, or god knows what). G R E G G E D

      My R32 Money Pit & The Headaches That Come With It

      Very interesting, im not sure how all those complications fit in to running a haltech instead of a stock ecu but I'm starting to think I'm a bit out of my league.

      My R32 Money Pit & The Headaches That Come With It

      By GTSBoy · Posted

      I just put 2 and 2 together. This is a Neo converted R32. The Neo ECU (in concert with the R34's AC controller) runs the AC quite differently to how the R32 ECU and AC controller do it. If you just drop it all in, it won't work. There is some tricky wiring required, including changing to the pressure switch that the Neo controllers want to see. I don't know what it is, because mine was done by a guru. It was a year or so after I did that transplant before he worked out what needed to be done.
