NicT Posted November 2, 2010 Author Share Posted November 2, 2010 Finished the exhaust, old rusty 3 inch from the headers back to the diff. Then stainless out. Sounds sexual. Have fitted an alloy radiator, tig welded stainless waterlines, and tig welded a new intake pipe and made an adaptor plate for my air filter. Driven it a bunch of times and have discovered a terrible problem. Car revs and goes hard from 0 - 3000rpm, then it hits a soft limiter. Also when i open it up on wide open throttle it just shits itself at any rpm. But ease on the pedal and she cruises happily up to 130kmh in 3rd (on a 4 gear auto). Getting there but i wouldnt deem it road ready yet. Pictures: Quote Link to comment Share on other sites More sharing options...
EvoBilly Posted November 4, 2010 Share Posted November 4, 2010 is it the traction control playing up as it wouldn't be getting any signal what the wheels are doing remove the traction control butterfly from the inlet Quote Link to comment Share on other sites More sharing options...
Simon Posted November 4, 2010 Share Posted November 4, 2010 Do you have a speed input from the gearbox? Is it going to the right place? If the ecu thinks the wheels are not turning / its in park / neutral it won't make any power. But I thought you have the ECU that is separate from the AT ecu.

NicT Posted November 5, 2010 Author Share Posted November 5, 2010 Traction control is disconnected. And i am running a UCF10 ECU which means the auto trans and ecu are in one box. The check engine light isnt working atm so need to sort that first and try run some check codes. The gearbox speed sensor should be connected to the ecu at the moment. But even so the engine should free rev up to redline. Quote Link to comment Share on other sites More sharing options...
Spencer Posted November 6, 2010 Share Posted November 6, 2010 Yea codes is the first bet, don't need the light if you have the check connector there just jam something in there. Know another UZ that had this problem, no codes, tried everything to rectify it but it ended up with a link. Never scoped any of the cam sensors or anything but was definitely a spark problem Quote Link to comment Share on other sites More sharing options...

Hooked up traction control too. I finished my megasquirts basic board, just building a second VR input and injector driver circuit for it. If i get no results ill just use that. Id be stoked to get a hold of a factory crown 1uz ecu but those are $$$ Quote Link to comment Share on other sites More sharing options...

NicT Posted November 30, 2010 Author Share Posted November 30, 2010 Got the Megasquirt wired into the car today. Deloomed my loom and threw 70% of my wiring out. Pretty stoked. Cars running rough as guts but i have vacuum leaks for africa. All outputs work great. Using a 12 - 1 skip tooth mod on the crank timing sproket. Will get video of a skid once its running.

NicT Posted December 7, 2010 Author Share Posted December 7, 2010 Fuck yea baby megasquirted! Bit of a missfire, but skids right up to 6500rpm so stoked Quote Link to comment Share on other sites More sharing options...
NicT Posted December 18, 2010 Author Share Posted December 18, 2010 Deloomed engine bay, wired up alternator, filled with powersteering fluid, tidied everything up. Been datalogging the last week trying to nut out this misfire, seems to be the MS recalculating AFR vased on my fucked o2 sensor (0 - volts out haha) so when it sits in closed loop it dances around leaning out and overfuleing back and forth. Will either program closed loop out of the the ecu, or find a replacement o2. Also discovered alternator doesnt charge. Opened it up to test continuity of everything and found slag from where they gas axed the engine out of the car, lots of melted copper windings and black parts. Safe to say its proberly toast. Otherwise car runs great. Really need to sort alternator as radiator fan screams through power keeping the beast cool. Pics: Before: After: Mmm Stainless If anyones interested in buying it, give me a pm. Proberly looking for around $4500 - $5k. Quote Link to comment Share on other sites More sharing options...

NicT Posted December 29, 2010 Author Share Posted December 29, 2010 Got a new toy today, hopefully have it in the car tomorrow so i can have a fiddle with my megasquirt. Wideband O2, MTX-L Gauge http://www.trademe.co.nz/Trade-Me-Motor ... 659347.htm Quote Link to comment Share on other sites More sharing options...
NicT Posted January 1, 2011 Author Share Posted January 1, 2011 Margarita hangover ment this small job took me 3 hours, just installing a gauge and swapping over o2... happy new years The old boy has a set of camzilla suction mounts, so might slap one on the side of the crown and take it for a skid for you guys.
