Swampy442 Posted November 21, 2010 Share Posted November 21, 2010 No, no, no. Stock ECU will only run stock 380s. Quote Link to comment Share on other sites More sharing options...
Guest s14a_1JZ Posted November 21, 2010 Share Posted November 21, 2010 i thought the stock 1jz yellow top injectors were 315cc? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted November 21, 2010 Share Posted November 21, 2010 Pretty sure theyre 380, anyway thats not the point lol. Quote Link to comment Share on other sites More sharing options...
Guest s14a_1JZ Posted November 21, 2010 Share Posted November 21, 2010 cheers, what sort of hp/power figures could be achieved using a single t51, front mount, e-manage, everything else left stock, Quote Link to comment Share on other sites More sharing options...
little num Posted November 21, 2010 Share Posted November 21, 2010 swampy thought the 1JZ would run supra J-spec 440cc just about, i hope it does as im fitting them in mine when i go single. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted November 21, 2010 Share Posted November 21, 2010 Emanage ultimate or blue? Theyre both quite old ECUs now, for the cash Id look at an AEM F/IC. With a T51 on stock fuelling you'll run out of duty cycle so 350/360ish? get UK Supra 550s and be safe for over 500 James not in my experience, if it does it will overfuel pretty badly on WOT.

little num Posted November 21, 2010 Share Posted November 21, 2010 well i suppose it might as well be me testing them, id rather it over fuel then run as lean as hell lol. Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted November 23, 2010 Share Posted November 23, 2010 Go for it James, only 1 way to find out lol. But given Toyotas tendency to overfuel on WOT (one of my Soarers was running 9s on full boost) I reckon its gonna really struggle. The stock ECU will run a single fine, Im running a T67 on a stock ECU right now, only problem is crazy fuel cutting on anything more than half throttle Quote Link to comment Share on other sites More sharing options...
little num Posted November 23, 2010 Share Posted November 23, 2010 Well im running 1.3bar on the Turbo Technics twins and my AFR on wot reads around 12.2 on the 380cc injectors and seems to pull really well my EGT'S are around 730 so not getting hot. Once i change the injectors to 440cc im going to try and push 1.5 out of them, ive just got my intake temp gauge so will see if they are just being hairdryers lol I did have a missfire as my plugs were gapped wrong 0.9 so i have regapped them to 0.7 and the differance was amazing.
