LittleRedSpirit Posted February 15, 2011 Author Report Posted February 15, 2011 Been thinking about redoing the top cover on the 20v. I'm thinking either clean off the paint and polish it to a shiny chrome finish or powdercoat it to a mettallic colour. Ideas? Anyone done their 20v top cover in a nice finish they can show me? I'm not a fan of black crinkle coat, so please don't suggest that.
mungi mods Posted February 15, 2011 Report Posted February 15, 2011 polish then clear powdercoat silver sparkle 2 powdercoat
spilmer Posted February 15, 2011 Report Posted February 15, 2011 ive used these guys before http://www.thermaledgecoating.com.au bit exxy though.
spilmer Posted February 15, 2011 Report Posted February 15, 2011 I had a go at doing your tacho mod, last night. No joy. Maybe the ecu isnt outputting the right signal ?
LittleRedSpirit Posted February 15, 2011 Author Report Posted February 15, 2011 I had a go at doing your tacho mod, last night. No joy. Maybe the ecu isnt outputting the right signal ? Bring it to the shed Ill have a look at the board in the tacho and see how it matches mine. Did you swap the resistor and the capacitor? You will find the tacho control settings under the first tab in the software, triggering modes, then the button for setting up triggering. There is a drop down menu for ignition 3 output and should be set to tachometer 50%dc. You might need to ring Anthony and see if he set your ignition up as full sequential like he was supposed to for me but didn't. If he has done this ignition 3 output would be used for ignition and as such he would have run a tacho wire from a different place, probably an auxillary output. Send me your map and Ill see what he has done if you want.
LittleRedSpirit Posted February 16, 2011 Author Report Posted February 16, 2011 Priced up ceramic top cover treatment. $120-150. Not too bad, reckon Ill go with that. Needs 7-10 days to get it done, anyone have a 20v top cover spare that I can borrow for a week or 2? I just had a play with the tune once again, my economy is almost where I want it, performance is increasing. The adjustments I made then were designed to give a better surge from 4500rpm to 7000rpm. Definately achieved some good results. Ive also been focussing on working out a flat spot at 3500-4000rpm, its not really flat, it just builds better on the map above and below. Ive made some adjustments, and it seems better, but I will need some decent highway miles to really tell. Its all good fun!
spilmer Posted February 16, 2011 Report Posted February 16, 2011 i have a spare, welcome to use mine. tacho is working now - was using the wrong wire to the gauge. whoops.
LittleRedSpirit Posted February 19, 2011 Author Report Posted February 19, 2011 Just had an awesome drive with Spilmer. Did a bot of a tour of the MT Crosby/Kholo area. Some tasty roads up there.
Evan G Posted February 19, 2011 Report Posted February 19, 2011 paint your front end :rolls: both still look the goods
mhmills Posted February 19, 2011 Report Posted February 19, 2011 Reminds me of my mates ex-Ksev, which is now owned by RX-747, a member on here... Looks good man!
Trev Posted February 20, 2011 Report Posted February 20, 2011 how much were the disc brake cables Matt? need to get some myself PM sent.
LittleRedSpirit Posted March 2, 2011 Author Report Posted March 2, 2011 Got some bits back from the powdercoaters yesterday. I now have a neatly coated bonnet post, and Stone tray. No more rusty oily stone tray in my engine compartment. On the negative side, I think after several years of abuse, including being crushed into the strut tower when I carashed the red beast, the 540cca battery Ive been using is slowly dieing. If the car sits for 3 days with no use the thing wont start, but a push start and the alternator soon charges it up enough to start. Then 3 days later, no start. Its problems are probably exacerbated by the 1.0kw starter motor I just fitted instead of the .85kw unit I was using before. Also Ive been playing with the tune and have done more to work out the small power flatspot at 3800rpm. Is pulling a lot better there now. I might try and put it on a dyno and just do a power run with the 02 probe up its butt to see how the tune is going.
LittleRedSpirit Posted March 4, 2011 Author Report Posted March 4, 2011 So it seems my battery isnt dead. Its a trusty workhorse. I found an absolutely f@$ked wire right at the battery terminal. It must have had acid on it in a previous life as it was rotting the pins in the plug, and it was the wire that feeds the whole ignition key and dash area. This explains why the lights were sometimes not switching on, the key obviously wasnt supplying enough voltage to trigger the starter either. It seems lively now, so I've booked in to put it on a dyno and do a power run and O2 reading. This should give me some more ideas for tuning and finding some more fuel economy. Ill post a video of her wide open on the dyno later today. Also will put the chart up and see how its doing. :cool:
LittleRedSpirit Posted March 4, 2011 Author Report Posted March 4, 2011 Ok, just got back from some dyno time. We did a power run, found it was a bit lean right through, just about half a point average. It appears my interpretation of a happy sounding motor is one pushed close to the edge. Added a lot of fuel aspecially from 4000-6500rpm, as it wanted a lot more and just kept making more torque in that range. Its an interesting chart, and it confirms that my modifications to gain torque have worked. Compared to my old dyno chart I am making a lot more power earlier. It also made 88KW on their scale, it made 85kw before. So it has made more power earlier, infact, with the combination of a 2 inch exhaust pipe, 4-2-1 extractors, and 30mm long 42mm diameter trumpets on silvertop throttles, it makes its peak power at 6550rpm, a full 600rpm sooner than it used to. So to summarise it makes more power earlier. This means the area under the curve is quite large compared to the old system. I will plot the 2 graphs onto a shared scale for comparisons sake to exemplify the point more clearly. Its making 100hp at 5450 rpm. Thats sure putting ts power down differently than before. See chart below. Videos to come when I tube em.
