Re: Waste Gate Duty Cycle Found some notes I printed out from BG on data master values and he agrees that the parameter is 0 to 100. 100 being fully closed. I just never had it open all the way before, but I don't have a lot of DM runs racked up yet. It was also weird that there was just a step...

Can the waste gate duty cycle go to 0%. I have a SY137A chip and I am only used to seeing it go to about 69%. On a run I made today it went from 100% to 0% and back to 100% without any numerical change in between. On the last engine take out, the WG bracket did get bent but I managed to bend it...

Flipping through JC Whitney the other day (because I dig the product illustrations) and saw and ad for CO2 systems. They sell portions of intake tubing, fuel blocks, and halos that mount in front of the intercooler. I guess the idea is to pump CO2 through the components to cool the fuel, the...

Re: My oil Leak (pics) and need a suggestion Mike, I had the exact same problem with 2 Fel Pro gaskets and I have no blow-by. Has your set up worked since putting new gasket in?

Re: Defective Oil Pan Gaskets Couldn't find torque spec so I used around 15 ft.lb. Guessing it is should probably be less maybe even inch pounds????

Anyone else had trouble with Fel Pro Oil Pan gaskets spliting down the middle of the rail. It completely blew out of the side of my block causing an oil leak. Pulled motor and bought a new gasket, torqued it down evenly, pulled pan off again to check it and it was also cracked Any alternatives...

I have a sy motor in my 90 s10 and the stock downpipe and oil pan fit in fine. The ac lines are a little close to the intercooler though. CTA

Strange that the s10 would have an extra wire but it sounds like I won't be needing it anyway. I guess as long as I wire it per the SY diagram it should be fine. Thanks all.

Just checking out the wiring diagrams for the tcc and I am a bit confused. The regular s10/s15 with a 4.3 and 700r4 has three wires to the tcc: lt blue(446), tan/blk(422), and ppl(420). The syclone diagram only shows the tan/blk and ppl. The diagram of the tcc circuit is identical on both the...

After clearing the code 42 it has never returned. I'm a little baffled but I'll check the knock sensor wires and make sure eveything looks o.k. If I replace it, is there a torque spec? Seems like I once heard that getting the sensor too tight would cause false readings??? Could be an old wives...

I seem to have some very low timing values (4 - 7 adv)at WOT/full boost. Also the rpms are very low (3000) at 100% TPS. Here's the scoop: 2wd with 3.08 gears, approx 1000 miles on rebuild, new cap and rotor (conrad), plugs and wires, 93 octane, high flow catco cat, dynomax muffler (all 3" behind...

jwaller, Sorry about my misplaced reply earlier. To answer your first question: the trans is completly stock, the upshifts are pretty firm when cold and seem to be just right after everything has warmed up. Also, I do not think the lock up solonoid is functioning as it does nothing when I jump...

???? why would this be an issue if it downshifted behind a TBI 4.3? Really the only thing that is different is that I now have a Syclone engine, stall, and tv cable.

Does anyone know why my 700 does not downshift when I floor it? I have adjusted the tv cable several times and noticed changes in shift points but for whatever reason this thing won't do a forced downshift. I can be going up a hill at 20 mph in drive and the thing won't downshift to 2nd...

I have heard the stock chip disables boost for the first acceleration. Does the ATR Sy137a (pitbull) have this trait as well? Thanks in advance, Clayton

When Datamaster signals that the TC has locked, is it just taking the lock signal from the ECM or does it actually "know" the TC has locked. I am not sure that mine is locking but it appears to according to my data from Datamaster. Also when I turn my manual lock switch on, I don't hear the...

Forgot to mention that you may need to replace TV cable and throttle cable. Clayton

Not sure how your stock fuel lines are routed but I had to run braided line to the motor since my TBI truck had a weak fuel line set up. Replaced stock pump with a syty pump but a Walbro would be better. Also the sy/tys had a higher stall converter than the stockers. While motor is accessible...

I rebuilt the motor and turbo. It started and ran really rough. Gradually got to where it would not start at all. It acts like the timing is off but no matter where the distributer is, I still get a slight kickback. My local shop is stumped but they are convinced it is somehow timing related...

Your are right. For 8 bucks I just replaced them. Didn't realize stock rollers were that cheap.....
