If your budget is so tight that $80 means that much, maybe this type of project isn't for you. Personally I'd much rather do something right, the first time.

The Import Muscle speed sensor kit replicates the sensor pulse in the OEM transmission, using an OEM sensor. It's doing exactly what Honda designed it to do. This allows ABS and EPS to work perfectly. Exactly how is that "ghetto"?

Just let this guy try the Honda Cmc he must not get the principles of hydraulics....... Which I guess is fine, and I also don't get how the 2 wire sensor Is going to Feed the proper 5v reference to the cluster... a 3 wire sensor is much more accurate .... Not happening .... But again let him try !!! Hahaha not to mention we learned the Honda systems don't like splitting up the signals so both the abs module, the eps module, the cluster, the soft top ecu etc will all have to accept the signal from his 2 wire sensor......

Good luck and FYI the import muscle stuff is top notch !!! Ghetto it is NOT..... My speedo works, my eps works, everything works period

AND a used harness is 300 fine ... The one racerX bought is 585 base price, plus o2 wiring, plus injector clips, so 650-700

Just for harness and ecu ........so I don't get the cheaping out of a cmc or the vss set up


Weird priorities

RacerX we are not trying to bust your balls for thinking outside the box which is how we got to the point we are at now. We are just trying to save you some time of trying things that have already been tried. I meen you must have some faith in us since you bought the rest of our kit. I would hate to see you go through what others already have done. Keep in mind that ABS could also cause other issues with the car such as the EPS working right. For instance if you slam on the brakes and the one wheel your pulling your speed info from locks up your EPS now operates totally different as if the car is sitting still since it no longer see any speed and may cause the ABS act weird as well which could make avoiding an accident or just controlling the car in that situation a bad situation. Again best of luck, we are always open to improving our kit if we can.

Ya man no bad blood here outside the box is who us ls1 swappers are ..... But the headaches associated with this stuff can be very large we are just trying to help you out !!! Again good luck !!! Hope things do workout for you, and xyster is correct if 1 wheel locks (the wheel you tapped in to) even if it does work it's not a reliable signal .....

For get about the cluster the eps is my main concern as well.

Here is a link to the harness I bought...

I suppose "ghetto" wasn’t the appropriate term. But IMO, I would PREFER not have a reluctor wheel spinning exposed under the car. If it comes down to it, I have no issue shelling out the money for the I.M. kit. Im just trying to find a potentially better way of doing it. "May require the purchase of SpeedoHealer (healtech-electronics.com) to calibrate your specific vehicles needs", (which is listed on the website) made me assume if you wanted a truly accurate speedo, then the speedo healer was required.

I understand that the EPS system on both my 03 Si and S2000 are sensitive systems. Anything I try will not be a permanent modification. I have the both factory Honda manuals (electrical and mechanical) and will be cross referencing schematics.

As you said, thinking outside of the box is all im trying to do. You have made several improvements to your kit since the beginning. Getting away from the Aeromotive FPR and switching to the Corvette FPR/filter is a huge improvement! With that said, my job title literally is "Continuous Improvement Specialist." I get paid to question process and equipment, brainstorm, prototype/rewrite, and then test! Some changes save my company hundreds of thousands of dollars a year. Some things fail and its back the drawing board. Long story short, I’m simply trying to improve the knowledge and information concerning swapping an LSx engine into the S2000 chassis.

Yes we mention the speed heeler only because some guys may have different gears in their factory S2000 differential example 4.77 instead of the stock 4.10. In this case they would need to dial it in some. The problem with just adding a speed heeler is that the Honda is looking for about 159,000 pulses per mile and the GM only sends on like 17,000 per mile.

I completely understand why a speedo healer alone doesn’t work. The correction factor is beyond what the healer is capable. Another idea, is running 2 speedo healers in succession even feasible? I imagine since it would be 2 amplified signals, it would cause a "glitchy" speedo reading...

To go along with my idea of using the ABS wheel speed snesor. When i get home ill pop the wheel off the car and count the number of teeth on the reluctor wheel for the wheel speed sensor. If the 2 wire signal from the ABS sensor cant be read by the factory ECU/cluster, there MIGHT be a chance i could build a bracket to mount a factory honda VSS on the hub... I just need to get the wheel off and look at it. There might not even be enough room to mount another sensor... IDK, just throwing ideas out there!

xyster

I looked at that route first. You'll have a heck of a time finding a location to get something mounted that would not interfere with suspension and turning and just getting the sensor In the right location first off. Then you have to deal with getting it sturdy enough so the the vibration and suspension moving doesn't effect the gap which is very very small to begin with. Again I commend you for thinking outside the box but if it is only different an not better is it worth it. Two speed heelers, a custom bracket to hold sensor on a very abusive part of the car and so on. Like stated before our speedo kit works just as if it was in the Honda transmission. It reads a gear and sends a signal.

So, the ABS ring on the front wheel has 50 points. With 215/45/17 tires having a height of 24.62"/circumference of 77.346", 63,360" in a mile, would give you 819.176 revolutions per mile, times the 50 points equals.... 40,958.8 pulses per mile. So, a correction of 3.88, compared to the GM sensors 9.35. That SHOULD put it within the capabilities of the speedo healer.

I do agree that there is little to no room for an addition sensor to be mounted to the wheel hub without modifying the hub, and in turn weakening the hub... So, the idea of running a second sensor is not a logical option.

The heads should be back from the machine shop tomorrow or Monday. I'll toss those on next week, modify the headers as much as I can to get them to hug the motor as best as possible, then the motor will be ready to be put in the car. The only parts i don't have yet are the exhaust fab parts and injectors. If i'm feeling froggy, maybe ill mess with the speed sensor stuff before i go to put the swap in. Theres a local dyno meet April 6th i was thinking about taking the s2000 to and get one last dyno run on the f22. It put down 213whp when it was stock, so with the bolt ons since then, im hoping for tad better numbers and it will help the motor sell!

As far as the K.I.S.S. comment. Is it not simpler in the long run if WE (the guys doing the swaps) find a way to better utilize parts/money/time for the rest of the community? Hell, if i can get the ABS based speed sensor to work, it could save 1 extra step and $400 for people in the future. And if for some reason a miracle happens and the speedo is dead on without having to get a speedo healer, (which the math says it wont) it could save people with geared rear ends money also... Im not saying the import muscle kit is wrong, im just wondering if there is potentially a different way of doing it. Actually, I was criticized for buying an aftermarket wiring harness to save time with the wiring... HOW THE HELL DOES THAT WORK?!
