problem solved. removed the link altogether. of 8 years of ownership, the link is by far the biggest disappointment of anything i've put in this car.

Douglas; Steven Krause Cc: [email protected] Subject: Re: link tuning issues Low or no output at in row 1 is a common symptom of the O2 heater being either unpowered or burned out. Tip-in stumble is usually caused by zones 205/210, 305/310 (and for n/a 405/410, 505/510) too lean. Or it will bog if too rich. The most common cause of low IAC duty cycle is a small vacuum leak. It's easy to find if you plug up the IAC air inlet hose and block off the TB air inlet with a jar lid (with a rubberized seal). Your overrun value should be set about half way between your idle map and your minimum map seen during overrun. Then raise it just until the throttle start to feel like an on-off switch at tip-in and back off two points. Boost targets are irrelevant in n/a mode. ? does indeed mean that you're too far from a zone center to tune in fine mode but coarse will still tune the closest zone. L3 should not be used until fine tuning has been completed well. If you can datalog you can tune much faster because you adjust many zones by hand based on estimates from the log data. ----- Original Message ----- From: Chad J. <mailto:[EMAIL PROTECTED]> Douglas To: Steven Krause <mailto:[EMAIL PROTECTED]> Cc: [email protected] Sent: Saturday, May 24, 2008 8:06 PM Subject: RE: link tuning issues Well, if your O2 is reading lean for some reason, that sure could explain the huge spike in all your zones. I'd check your O2 sensor connections to be sure it's working right. Do you have access to the equipment to grab a datalog and post it to the list for folks to look at? Did you double-check the MASTER FUEL setting to make sure you entered it correctly? What chip version are you running? If it's old enough, there might've been some changes to the way your chip uses the defaults as well. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steven Krause Sent: Saturday, May 24, 2008 10:28 PM To: [email protected] Subject: link tuning issues the car is a '92, n/a with stock injectors. no knock sensor. i manually input the recommended defaults on the flying miata site. the car runs well, but i have a few issues: #1 the car falls on it's face when i leave from a stop. if i don't blip the throttle first, it will stall. the original settings i had tuned the car at did not do this. #2 when i put the car into rough tuning mode (L3 off, lambda on), the values in zf100 spiked 66 points over the value i entered (was set at 110, went to 176. when i checked the zf600 row, zf610 on through, these values had also spiked 30-60 points each over the values i had entered. #3 my overrun value has been low in both modes i have tuned. mine is 12. #4 the tuning manual says the boost targets should be set to "100", the flying miata preferred desfaults all say "255", mine were at "0" #5 in rough tuning, looking at the keypad, i'm getting a lot of "?" and "lambda X". the tuning manual says the "?" means the fuel map isn't centered. my o2 reading (it's a four wire) reads 0, sometimes is dithers to the low-upper 70s, but it's mostly at 0 @ idle. #6 the highest IAC duty cycle i can acquire is 19% at idle with the ilde screw closed all the way. the car runs smoother with te FM defaults over mine, but i need some help to clear these issues. please help. regards, steven _____ _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
