just read this frm start to finish :O great wrk here .. glad to see anothr n16 5 door hatch ;) even if yours is 10000000 bhp more than mine haha

it's not at the moment. haha.

we are having MASSIVE issue's with the tuning. I think it all comes down to software knowledge tbh. I'll be ringing uprev in an hrs time, to try and work out whats going on, and how to solve the issue.

the issue me and the tuner are having is in the fuel compensation table, we cant alter the base fuel schedule axis high enough. From the reading i've done, I think this comes down to the fact we've altered the injector table, which in turn affects the MAF table. From my basic understanding is, they both correlate together.
 
Yea so am i mate.

I'm starting to get rather frustrated with how long its taking to get tuned, but i'm slowly starting to get my head around how uprev works.

UpRev's customer support is virtually non existant. This becomes rather annoying.

from my basic understanding, to tune the car, you dial in the k fuel multiplier for the larger injectors. Once the injectors are scaled correctly you need to adjust the afr's using the MAF table or fuel compensation tables.

this is where it becomes difficult. you can't real time tune the maf table, and you can only increase the base fuel schedule(k fuel value x MAF value = BFS) axis in the fuel compensation chart so far.
with the tracer flying off the fuel compensation chart, you need to go back and readjust the maf table.
once the tracer is keeping within the chart on fuel compensation, you can fine tune the afr's using the maf table.

my tuner ran into some difficulties with changing the maf type from stock to the gt uprev. so thats where my car has sat for 2 weeks. I went out there yesterday and had a quick play with the car off the dyno and fixed this. I've asked my tuner to give me enough notice to get out there next time he's putting the car on the dyno, so we can move past any little issues that may come up.

UpRev is a real learning curve for myself and my tuner. It's not easy, because i've got absolutely no tuning knowledge, and for my tuner, uprev does alot of things backwards to what he's used to with haltech.
 
137.6kw atw is the final figure. Haven't picked the car up yet, but I will in the morning. Can't wait to get it back!
 
yea, im pretty stoked. he's said theres still room to put more timing into it, but because of the way the timing tables are in uprev, he said it'd take a fair bit of playing around to get that last little bit out.

Next focus on the car is to work out how to retrofit cruise control, for map switching. I've found the correct part numbers for the clutch/brake/steering wheel switches. I'm still awaiting a response from uprev to see if my rom file has cruise control enabled. once i've got the map switching sorted, i'll look at running a 2nd map with e85.
 
Just on my way to the workshop now.

I've just been over a few old threads on PGA, and I can't complain with the power.

The exact same turbo/manifold/dump made 130kw @ 10psi on the old car(albeit it was a ph1 qg18, and only had fuel control)
Another ph2 qg18 made 134 @ 11.5psi using a full standalone ecu. (same tuner and the same dyno)

I think the next stage on the car is brakes, then interior/exterior mods. After that I'll buy a 2nd motor and build that. I wanna push the boundaries of the qg. I'm going to aim for 300whp. On a fully built block.

adam also said a good upgrade would be to get an lsd. he seemed a bit shocked once I told him its already got a nismo 1.5way mechanical diff fitted. he said something mustnt be right. so i've got to get that looked at and go from there.
 
That is silly torques for that power and displacement. Impressive. Showing up a few SR20DE+T's there.
 
yeah at the 4000rpm point the graph shows about 430ft/lb so 430x4000/5252 = 327bhp which is about 244kw, and I thought the US graphs were funny :-/

so if your 183bhp was at 6100rpm (which is hard to work out as he backs off and accelerates again at the end) you would have 183/6100x5252 = 157ft/lbs
