spudly13 Posted June 21, 2012 Author Report Share Posted June 21, 2012 cruisin trying to stay out of boost, im sitting at 12-14afr. which is pretty good is it not? when i start to pull, say second gear full boost, my afrs go to between 9 and 10, correct me if im wrong but thats richer right? So if im running richer under full boost, i need to do one of two things, reduce the pitot tube size, less pressure less fuel under boost, or go to a slightly smaller main jet. im sitting at 1.9 right now, which is big for my 1.6 compared to everyone else, so meybe a 1.8 or 1.75? Edit: or just run it for ahwile rich under boost, a little extra fuel couldnt hurt anything right? Quote Link to comment
Farmer Joe Posted June 21, 2012 Report Share Posted June 21, 2012 how many pounds of boost is there being introduced? 9-10s in the afrs is a bit rich... you could get a little more power with tuning it (your smaller main), but i think youve got the right idea about keepin it rich.. does it pull smoothly going through the different circuits on the carbs? are there flat spots or anything? are you getting alot of fuel smoke out the exhaust?

VintageRice Posted June 21, 2012 Report Share Posted June 21, 2012 Dude. Ur dead nuts. I'd stay right there. 14 is perfect for efficiency for cruising. And you want to be a little rich under boost. Around 12 I believe. Keep it!! Quote Link to comment

Im boosting 8 pounds, and its there whenever i punch it. Overall it seems to be running good, pulls good, no flat spots at least not that i can tell, theres a bit of lag in between gears, and no smoke at all. i can smell fuel occasionally but theres not enough there that you can see it. Bov is now working fine. i think today i will get the cold air finished, and finish my exhaust, both of which could have an effect on tuning, and see where its at before i try tuning it at all. Also going to re calibrate the wideband just for the hell of it and make sure its right. Quote Link to comment
fo0manchu Posted June 21, 2012 Report Share Posted June 21, 2012 make sure your not running to rich, it can wash out your cylinder walls. Smell your oil to make sure it doesn't smell like gas. 9-10 is really rich. Quote Link to comment
Farmer Joe Posted June 21, 2012 Report Share Posted June 21, 2012 right on... yeah if you can get it into the 12 range, i think youll have yourself a nice little combo.. Quote Link to comment
VintageRice Posted June 22, 2012 Report Share Posted June 22, 2012 I drove mine again tonight. Dang thing runs better every time I'm out!! R1's FTW! Quote Link to comment
spudly13 Posted June 22, 2012 Author Report Share Posted June 22, 2012 hmmm lol well im glad yours is runnin good, mine gets worse everytime i drive it HAHA oh well, its just all the little fine tuning bs that i have to get past. i think that tomorrow...since i shouldnt drive it... ill go back to suspension for a day and see what i can accomplish.... If anyone knows where i can buy aftermarket floatbowl t's (i read somewhere they make them) let me know, until i get new ones my cars down! Problems of the day. broken float t. headlights shorted on something and now there all f***ed up, somehow engine bay temps reached 140 degrees = a big problem, boost leak somewhere, i tried shortcutting cleaning my engine bay....super clean and aluminum...enough said. On the bright side, Bov is working great, afr seems to be working great, and up until the T it was running like a champ, everything seemed to go downhill after taht. Quote Link to comment
spudly13 Posted June 22, 2012 Author Report Share Posted June 22, 2012 Oh and to top it all off, i think my front drivers side bearings are going out, and i think another axle u joint is going out, time for some much needed dd boring tune up stuff i guess.... Quote Link to comment
