"For 6-cylinder Tacoma, 4Runner and many other Toyota applications. It calibrates the 0-5 V MAF sensor signal and intercepts the variable reluctance cam and crank sensor signals. This unit is has an internal enrichment module that works with either narrowband O2 sensor or wideband air/fuel sensors. The module allows a richer fuel mixture in boost at part throttle.

The R4 software is included with this unit."

It said they used the FTC1-017B on the ISF build but I don't see that one on their site. Maybe they meant FTC1-017D like on the website

They delayed the timing by 6 degrees by delaying the crank trigger sent to the ECU.

Also clamped the MAF sensor to 4.6v so it wouldn't cut fuel but I could do that with a 4.6 volt zener diode in series with the output wire for the MAF which would be simple

im so proud of you for reading that. most people wouldn't of even taken the time. than they would have kept asking questions and bothering other people when the actual proof of the products functionality is presented on a working and functioning car. good job!!!!!!!
And on the topic of the 6 cylinder device being on a 8 cylinder is as simple as the guy that runs split second is an engineer and brilliant so he could of easily modified it to work with 8 cylinders but if you think about it, the cam signals dont matter on the number of cylinders. just the rotation speed of the cams vs. rotation speed of crank. its not controlling any injectors. just skewing maf signal, voltage clamping maf, and retarding cam. He now has a device though thats capable of advancing the timing. some would be skeptical but he said he literally captures the cam crank signal and slows it down 720 degrees than can advance it from there. and it works.

one more thing. you dont need to go screwing with the maf clamp until you actually have a problem. the simpler the better. im running 9 psi. with out any voltage clamping at all and i know im over five volts easily. the beauty is, the factory computer is still using voltage over five volts to calculate air flow. at my current flow rate at wide open throttle im at about 5.6 volts and not setting any maf performance codes or fuel cut.

badblackgs, I haven't been following very closely, but are you running FI on a stock ECU?

yes, kind of. if you are interested on reading up on it my post "roots blown gs430" has everything you need to know. just allow some time to get through it.

Thanks bro, I'm so thankful for that info you shared. I read it all. I thought it was cool as hell.
I think a large reason of our success is that we tune around the factory ECU rather than trying to fight it, and that article proved it like you said.
Only us drivers "really" know what fuel/air is going in the engine by safely measuring it outside the ECU with boost and AFR gauges.
We just manipulate some things to prevent the ECU from knowing the difference and freaking out.
If you really want you could rip the ECU out and put in a standalone. But it will take a while, you will lose many features, and possible have driveability issues all the time.

Yeah youre right about the voltage clamping. Now that I think about it, I don't need to, because my piggyback clamps it at a voltage at what I set anyways.

I'd highly recommend reading badblackgs' roots supercharger thread as well as the single turbo thread. Both very interesting and I've read both of them page to page

I emailed split second. I want to know: 1) If I can use that unit strictly as a timing retard device from the crank/cam. I want to know if it will work with out freaking out if I don't have the the O2 sensors spliced in, and MAF (install instructions state this) because I don't want it to interfere with my well-working piggyback unit. 2) If the FTC-017D is the updated version of the FTC-017B. The old tacoma guys with the TRD superchargers were using the same FTC1-017B as the ISF guys used. Although again only the FTC1-017D are on the site.

So I received a response today from split second. Here is what he said:

Quote:
The current revision is FTC1-017D. This is set for 6-cylinder applications. You can use a standard FTC1-017D, but the retard will be 1.5 times the indicated value. I think the FTC1-017D/4 would work properly. It is set for 4-cylinder. That will work because we use one of the IGF signals as a tach input. The V8 engines use a pair of IGF signals that each pulse at a 4-cylinder rate. You could use it for timing retard only. I can take your order for the FTC1-017D/4 by email.

dont skimp out on the o2 sensor skewing. its a big help for overall transition from closed loop to open loop. i know bc ive done alot of data logging to see how the fuel trims react when its activated. its the perfect transition to open loop bc the factory ecu sees a lean condition and throws more fuel right at the same time your adding fuel for boost to go richer. so they both work together seamlessly when its set up right. i tested my enricher module the other day by unplugging it and putting in the bypass and watching my afr gauge. it was obvious it took longer to go richer and stay there. make sure you hook up the o2 signal wires. WORTH IT.

Thanks bud, I think I'll just keep my setup the same for now, I dont hear any knock even on these 100 degree days. If it is detecting knock and retarding, I cant notice any power difference.

Here are some quick videos, Since them I have deflated my rear tires a bit. If I roll into the throttle to 20mph and stab it, it would spin. Actually anywhere below 40mph it will. I haven't drove it with the less rear tire PSI but it has to help. I have to be careful launching it, it's quite the difference from stock. Ill get better videos out too. Exhaust clips, drive bys, etc.

Vid 1 is 0-60 (rev limiter 1-2 bounced a tad but still not bad), Vid 2 is 80-100, and Vid 3 is them spliced together

I also got new 2012 IS350 wheels with 300 wear sticky summer tires already on them. Perfect condition, the owner only drove them one year before putting aftermarkets on and gave me a great deal. They look so much better than the completely rusted 2006 IS350 rims before. In fact they were so bad that the inner barrels would not hold wheel weights. They would always fly off, and the front two were bent anyways. So I'm really glad to not have a shake above 60mph any more!
I have some extra Michelin pilot super sports from the old rims though to put on when these other ones wear out.

I made an emblem as well with all OEM Lexus/Toyota badges. I bought a brand new 2010 "SC" portion of the "SC430" badge and cut the "S" and "C" apart. I was looking for something to use as the "/" in between to make the complete "S/C" badge. One day driving around at work I got stuck behind a Rav4 in traffic and knew exactly. I cut the "/" part out of the "v" in that emblem I bought and trimmed it. I then heavily sanded all emblem piece edges and surfaces and painted them with Satin Black engine enamel. I have to say, I really like the way it turned out.
