lookforjoe Posted October 21, 2011 Author Report Share Posted October 21, 2011 It's such a slight decrease, I don't see how it could really make a difference; it's also post MAF sensor that it does this..... Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted October 21, 2011 Author Report Share Posted October 21, 2011 3rd Gear Pull early this morning. Steep uphill grade. Definitely too lean up top, I'd have to say power drops off over 7500. Inj duty cycle appears to peak around 7600, then tapers off ever so slightly. IAT scaling is all out of whack again. Ambient temps were in the high 50's low 60's at the time. I'll have to richen it up a little. Slower, too, but that may just be the steep incline. Timing looks great, so I think I'll raise the boost a little, once I get rid of the lean top end. Quote Link to comment Share on other sites More sharing options...
Jardim Posted October 22, 2011 Report Share Posted October 22, 2011 8400 RPM huh? 100 RPM more and your reaching BTCC status Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted October 26, 2011 Author Report Share Posted October 26, 2011 sleeved PP dowels done... still shouldered so no way for them to walk out. After talking with Ben last night & saying I was just gonna drive it the way it is for a while , I did a couple of pulls raising the boost only .1Kg.cm2 (from 1.2 to 1.3, approx 18psi) I think I need to reset the Apexi "NE Speed" RPM points - I have it set to limit boost to WGA under 4000, but I don't think I need that anymore, since I seem to have moved the whole scale up again with the new manifold & header. I didn't actually see over 18psi (logs underreport .5 psi max) until I shifted into 4th in the first run, and not at all in the 2nd (didn't go very far up the rpm range in 4th as you see) Anyway, I'm curious again about injector duty cycle rates, sparked by the conversation in BMac's Build Thread - in my case I'm seeing it level off over 7500rpm - so, I'm wondering if that's indicative of power also tapering off, or just 'cos it simply don't need no more fuel. A contributing factor may be that in TT I can only scale the RPM up to 7600, so anything fuel or ign after that, it's anyone's guess how it's calculated. IAT's are reading in Volts only, I still can't get it to scale properly in ºF, even using the recommended resistance/temp values for the GM sensor I'm using EGT's also still read low by at least 100ºF, once I go over 1000ºF; below that they are accurate 3rd - steep uphill grade Red line is Inj duty - you can see where it drops & levels 4th - level grade I didn't see over 64% IDC here - but I also didn't go over 218 g/s MAF flow - which seems consistent from gear to gear (almost same IDC to MAF flow in 3rd at same rpms) Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 2, 2011 Author Report Share Posted November 2, 2011 Been playing cleanup after Saturday's snow storm. Power was out until yesterday afternoon & I went & bought a Honda EU200i Inverter on Sunday; took a few hours to make a suitable place (where it wouldn't get stolen) to locate & run it, rewire the furnace so I could plug it in, etc... Then I got sick from being out in the weather. No work the past two days, so I've stayed inside as much as possible to recuperate. Anyway, I got a log of my heavy clutch slippage a few days ago - this is what is looks like on paper: you can see the drawn out peaks (yellow/gold) instead of the normal crisp peak & valleys this was on a steep uphill grade, but it will slip like that if I do a high rpm shift no matter what the grade. I'm curious what the pressure rating is on the S60R AWD pressure plate. I don't know if it will slip like that in 4th at similar RPMS, I haven't driven the car fast enough to find out. It doesn't do it on 3-4 shifts, even at redline of 8400rpm. I'm just going to have to go easy on it until I can make the time to install the Spec SO603F+ Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 10, 2011 Author Report Share Posted November 10, 2011 4th gear pull from this morning. Boost log is .5psi under actual data graph AFR's look OK - except for rich dip before going WOT... will have to do at least one more similar pull to see it that happens consistently. Timing seems OK, car certainly feels good! I'll be curious to see if the improves cooling to the extent of allowing more timing. Don't know if the cooling system responds quickly enough in terms of heat dissipation under WOT conditions to actually make a difference, or if it will be more of a general improvement...

fischmama Posted November 10, 2011 Report Share Posted November 10, 2011 Wait, so the rad is already installed? Damn you work quick. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 10, 2011 Author Report Share Posted November 10, 2011 Wait, so the rad is already installed? Damn you work quick. No, no I meant once I do get it in, will it make a difference compared to my current logs, as above.... Not sure when I'll get it installed, I'm supposed to be writing my MSEd Thesis at the moment...

lookforjoe Posted November 12, 2011 Author Report Share Posted November 12, 2011 a couple of pulls today. One just to document AFR's cruising in 5th-6th you can see how stable it is 3rd pull to check 60-100 4.99sec 2nd-3rd-4th pull to check 59-120 9.83sec 1 Quote Link to comment Share on other sites More sharing options...
bpray9223 Posted November 13, 2011 Report Share Posted November 13, 2011 Awesome stuff man! it's really interesting as always to look at your thread updates :tup: Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 19, 2011 Author Report Share Posted November 19, 2011 ^ Thanks! Another pull over several gears from a couple of days ago - trying to see how the AFR's & timing look over longer pulls. This was coming around an entrance ramp, so not the fastest times. Not sure why the timing dipped to 13.5 at 6880 in 4th... Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 22, 2011 Author Report Share Posted November 22, 2011 Tried running more boost -20psi on the same map. I don't understand it, but once I go over 18psi, the IBP log is not accurate - almost 2psi off in these logs. 3rd gear slower 60-100 than @ 18psi some crazy shit going on with the EGT's (black tracer) - unless it's a sensor issue... 3rd/4th gear - steep uphill grade - high EGT's in 4th, again, assuming it's not a scaling/probe issue 1st/2nd with raised WOT sliders - another crazy EGT spike Bottom line, timing pull, EGT's whacky. I'm going to go back to 18psi & leave it there for now. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted December 3, 2011 Author Report Share Posted December 3, 2011 Tried to install my new reverse-rotation 180AMP alternator today - wasted two hours This is where I had to shave the old alt for intake clearance Everything tucks out of the way nicely for Alt removal... BUT>>>>> because I used the newer style deeper breather box when I did the head - there is no way to remove the lower alt pivot bolt without removing the breather box.... So, I put it all back together & I'll have to deal with it next year when I have more time to dick around with it. Quote Link to comment Share on other sites More sharing options...
sconeman Posted December 3, 2011 Report Share Posted December 3, 2011 Oh fun :tdown: Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted December 3, 2011 Author Report Share Posted December 3, 2011 Oh fun Yeah - especially since I may end up having to remove the intake to get enough wiggle room. Definitely a job for next spring when it's warm out & days are longer again. 1 Quote Link to comment Share on other sites More sharing options...
