    You Have Tuning Advice For A 94 Cobra? Step Right In!!!

Tune it yourself with a Moates QuaterHorse. It's not brain surgery and you'll get the satisfaction...

    Tuning / data logging

    No, if you mean for your '94 - because it's OBD1 and the X3 only works on OBD2 and above. Your options are QuarterHorse and/or something like a Zeitronix wideband that will do A/F, Lambda, TPS%, RPM, MAF Volts, boost and another 0-5v source.

    95 Mustang GT...How Much Timing?!

    Spark adjustment is made in the borderline table. You determine where you want the spark curve to be and then make sure you are not running up against the max table. The only reason to use the global spark table is to PULL timing while you are dialing in the MAF curve for safety, then it goes...

    The .pdf is was done mainly for overseas customers because it is a real pain to have to ship them. I HAD to go with a company to produce them that would have some sort of copy protection - I have the Pro Racer training video (SCT) I produce copied all over the place - people even have enough...

    Just bought moates qh...

    It's really something that just isn't available too many other places. It took over a year to do, and it basically gives away all the 'secrets' of tuning. It's meant for tuning dealers mainly. Any low volume technical book of this nature isn't cheap. SCT's is $125, Greg Banish' SCT Tuning DVD is...

    Kenne Bell intake elbow question

    Years ago when I had a KB on my '95 with a 2.2 and a Flowzilla, I used this one: Trick Flow Specialties TFS-5150SN95 - Trick Flow® SN95 Throttle Body Adapters - Overview - SummitRacing.com I port matched it with a sanding drum. Worked well. The car (a heavy convertible, automatic) went a best...

    Gt idling issue... tried everything..

    If you are using the '03 IAC with the '99 PCM, the IAC transfer function is different between the two of them. A tune would help to negate it... Don

    What could cause one side of the motor to be richer than the other?

    In this case, it's easy - he has two widebands and one is saying lean, one rich. In the case of the PCM and fuel trims, it uses data from the two front 02 sensors. The rear 02 sensors are not in the equation, they are there to monitor catalytic converter performance. To put it in really basic...

    What could cause one side of the motor to be richer than the other?

    Of course that would help... but I have seen multiple individual injector failures on the dyno. It does happen. I run two widebands all the time, and have tuned tons of returnless vehicles - some really high HP and usually only see this problem when there are issues with the things I have...

    What could cause one side of the motor to be richer than the other?

    Could be a vacuum leak on the lean side. Or more likely an injector not firing on the lean side or stuck open on the rich side. Could be a BIG exhaust leak ahead of the sensor letting in atmospheric 02. Could be an ignition problem on one bank. Bottom line, could be almost anything. Swap...

    KAMRF constant 1.00 during CL

    A car won't go CL for several reasons. One of the reasons is the MAF curve is just too far off. I suggest you force open loop all the time, use a wideband to dial it into the ballpark and then re-enable CL and fine tune it. You cannot just load a generic MAF curve or one you got from somewhere...

    What is the best Tuner

    Huh? No, sorry that is wrong. You can buy a handheld wherever you like and any other SCT dealer can tune with it. You don't have to buy a software license, that only comes in if you buy the Pro Racer Software to tune yourself.

    20psi fuel pressure on boosted 02' GT

    On a returnless system, looking at FP doesn't tell you much, the PCM uses pressures drop across the injectors to maintain the target rail absolute pressure. You can log pressure drop with an SCT handheld and LiveLink, usually is 39-40.

    air/fuel ratio with 42's

    In closed loop operation the 02 sensors switch at the stoich point of the fuel and seeing as how most fuel nowadays is E10, the stoich point is 14.09 roughly which translates to Lambda 1.0. Most widebands are calibrated to give A/F based on the stoich point of pure gasoline, which is 14.64:1, so...

    few SCT tuning questions

    No open loop is still controlled by the base fuel table and any other modifiers in the tune. But for fueling to be right, the MAF has to be dialed in first. LOL on the other forum - be really careful as there is tons of internet misinformation out there. You need to get LiveLink going - if...
