Pnm35 Build Thread

[PN-Mad]

Oh, and found out I have the dreaded cylinder 6 oil leak! Oh well, doesn't stop anything running- sure put out a smoke screen last night!

I have got the idle running stoic at normal temperature. Still runs like a bag of shit though. At least I know it won't foul the plugs on the way to the tuner. Took it for a quick spin to make sure its drivable so its all good.

Question- what do I give it a tank full of now? I was thinking BP Ultimate, what do you guys think?

[Jetwreck]

BP ultimate.

awaits new fuel debate.

P.S. before you say it Scott.....we cannot get E85 everywhere for the 100th time!

United 100

James noticed that his untuned HKS V35 ran smoother on it. He then tried V-Power and the car was stuttering randomly when cruising. Dunno if it did it on BP Ultimate (I think it did), but for comparison he was quite surprised with how much better it ran on the United 100.

I don't see why you wouldn't just run 98 PULP...its not like you can crank up the boost if you do run E85 anyway....

Sure, not as many servos as us, we have about 20 now.

I guess we just buy more ethanol than you petrol heads...

Well, yeah, I can actually- but I just don't need 22psi to see some horsepower....

Both of them absolutely nowhere near us!

[scotty nm35]

Still, I would get both tunes. You guys seem to think I run this shit because it gives more power. That wasnt the reason at all, I wanted the detonation protection it gives and this is unfortunately what you require too now Alex.

[slippylotion]

Won't a good tune give him that! I've seen a few SR20de+T tuned by my mate and never had an issues with detonation as you tune it safe and correctly for each set up and situation.

It will be fine on 98oct

[scotty nm35]

Still too much load on the rods, you want to run the least timing you can which makes it run like ass. Better, slower burning fuel is the key, especially with high comp engines.

Of course it will be fine on 98 but for how long...

[PN-Mad]

Agree tuning is the key- which is why I'm using who I'm using. Det doubles or triples the load on the rods- thats what does them in. Idiot tuners jam heaps of ignition in them to bring them on hard- thats whats to be avoided as far as I can tell. Detonate on 98, detonate on E85- both will kill the motor, as it would any other motor. They just have to be tuned without producing overly high cylinder pressures.

Scotty- put it this way- by the time I went an bought a tank of E85, and drove it home, it'd just be about time to turn around and go to fill it back up. In the future, if it gets rolled out widespread around sydney- I'll think about it. I'm not keeping a fing barrel in my garage. This is a daily!

superchargedg-2003 coupe 5at-stock block-stillen stage 4-a couple more things-340rwhp on a dynapack(i dont believe it though) about 25,000 miles driven hard at times. 382rwhp and 396rwt on the greddy twins at 9psi. And its a 5at. 05/26/10 Update 82,000 miles FI'ed with 30,000 with the twins

Canadian - 2006 5AT Coupe. JWT TT @ 7psi ~370whp. Fast Intentions Exhaust, Defi Blue Racer gauges. Installed and tuned by Relentless Autosports. Built 5AT. Stock internals. 37k miles boosted 53k total.

voryGT-V-2004 Coupe 6MT, Greddy Twins,6psi low 350 whp and 10 psi 400high ,Fcon pron, plenum spacer, all bolt ons,15k on boosted motor, still running strong.

Mark350gt - 404whp 9psi. HKS Fcon VPRO. 750cc injectors, walbro fuel pump, and a bunch of other stuff. 13,xxx miles no prob.

These are a few of the poeple with higher kms. I'm a bit sick of people saying its a grenade. They got that rep because idiots in the US (and here too) didn't know how to tune them. Lessons have been learnt. I'm not saying its a strong as a VQ25, but don't underrate them either.

[WAGON_BOY]

good figures @ low boost

[ironpaw]

Well, yeah, I can actually- but I just don't need 22psi to see some horsepower....

Touche...

Who said anything about 22psi?

[bigkevracer]

+1 United 100. My car always seems to run better on it, not sure what the difference would be for a tune though, 10% ethanol vs BP Ultimate.

You only have two Uniteds with E85 in NSW? We have more than that! Plus even more when you factor in Caltex and Liberty...

[Daleo]

Good luck with the tune today Alex.

225rwkw.

Could also come down to the fact that my BCM is FRIED, new one getting fitted tomorrow

Agreed, and the same goes to the people that have a prob with the CVT in the GT8, 3 months since I strapped the turbo on and I havent had a single problem with mine.

[iamhe77]

Good luck today Alex. Look forward to seeing the result and reading the details

Possibly, and about bloody time it came in.

Give the service manager there a punch to the throat for me will ya

Oi bucket...

Can't wait to see the stats, let's see what life is in the car with the bowlers hat!!

[PN-Mad]

Turns out we were a little off

Things to note (no excuses! but various factors) Unigroup has whats explained to me as a "sad" dyno, not a Happy dyno like Envy Imports, Temp was about 31 or 32 in the cell by this stage. The Run was done in 4th Gear (unlike NM35s who use 3rd because of the speed cut)

Yavuz seriously knows his shit- as someone else had mentioned, dude is a scientist. He whipped out the calculator and estimated 175kw from my previous dyno sessions. Full boost comes on just after 2500rpm, and holds to just under 4 SPI by 6500rpm. That line you can see is 4 psi- sorry my photo is a bit crooked! Its pretty much full noise by about 4750rpm. Very nice flat graph.

AFR's are very conservative- starts at 12.5 and lowers to 11.5 by max RPM

Sorry, don't have a video, because I was in the car with Yavuz, going through the software. Very positive feedback from him re Uprev- comment was its much more user friendly than NISTune, and more set up like full after market (Link G4 / Haltech etc)

Someone must have snuck in and replaced my gearbox with a sponge when I wasn't looking- its gone to shit. I have the classic NM35 3 second wait before it snaps the next gear in manual mode. I believe that I can change this- the ECU has a torque management table - what we did to the base schedule was basically halve it (due to injectors and K value), so this needs to be applied to the gearbox too- the ECU tells the box when to expect max power, and adjusts the line pressures to suit. So thats a little project for me.

Hot start is acceptable- I have to work on cold start, as the car hasn't been cold!

So there you go- I'm a little bummed that I didn't crack 200, however its a blast to drive, the power is pretty instant, torque is great, it is (like every unigroup tune) a very safe and usable map. When done- the price was unbelievable. I actually paid him more than he asked, I thought he ripped himself off- told him to look out for me next time!

projects- plug the o2 sensors back in when its cold- see if the problem remains, cold start tuning, Gearbox scaling (will need mark from Abbeys help here), see how much I have left on the stock MAF, get upgraded MAF and shove 7PSI down it until something breaks!

SCOTTY- got your package today thanks. Hope nothing has melted-

Congrats on the tune; as you say, it's less about the number, and more about how it drives.

It was incredibly humid today, and with the temp it's probably not too surprising. At only 4 psi; I reckon you'd be happy with that.
