I was wondering if i remove the Vehicle Speed Sensor, will my jdm h22 not cut out at 120mph??? Im wonderin cause i have to let off the gas in tha quartermile so it dont bounce off the limiter when im spraying.
Please let me know what i need to do?
Thanks

 

It's not the matter of VSS. It's the ECU restriction.

 

if you remove the VSS, you won't know how fast you are going, you mean speed limiter. Get a USDM ecu or chip the jdm ecu and remove it in the program. BTW, what kind of setup do you have to hit 120 in the 1/4?

 

sounds to me like it would work, your ecu wont know how fast your going if the sensor was removed or just unplugged.

 

oh and I'm pretty sure that the sending wire off the vss splits up, one going to the ecu and one going to the speedo. maybe try just cutting the vss wire going into the ecu plug?

...and if I 'm right, Vtec won't kick in either because ECU think the car is sitting still at 0 mph. Correct me if I 'm wrong!

correct.

 

but isnt vtec driven off of RPMS, not the speed you are going? So if you disrupted the speed that he ECU thought it was going, then you could get by the fuel cut-off point? That is an interesting thought!

vtec is based on rpm, speed, engine temp, oil pressure, and the lack of certain cels. if you disrupt the vss signal you can get past fuel cut, but only if you can pull that hard WITHOUT vtec.

 

If the ECU thinks the car is stopped, its going to be the same effect as sitting still reving the car. You dont hit vtec when reving, sorry.

 

yep, no vtec if your going 0mph, waht you need to do is simulate to the ecu that your moving over 20mph, then vtec will work correctly.

 

I doubt you'll go over 120 on the quarter, even with nawws.

My guess is that he's upset that he can't break 120 out on the highway.

sure he can, just needs about a 200shot or so

thats exactly what i was thinking too. hahah

 

Im runnin a dc sports full exhaust, stage 2 cams, titanium valves,springs,retainers,5 angle valve job on the head, JE and Eagle Forged stock compression bottom end, stage 2 driveshaftshop axles, fuel rail, pullies,skunk2 throttle body and intake manifold (matched and ported), front mount intake, bf goodrich gforce drag radials and a nitrous express direct port kit (100 shot).My car is a 94 Honda Civic Vx hatchback with a JDM h22 swap.I have a slip right now from Byron Dragway in Byron Illinois last sunday.
12.26 @117.84 mph I can even post it up if ya'll would like. Im just asking for some helpful advice.Sorry

all that and you are on a stock jdm ecu?

 

get urself the s200 setup from hondata..... gets rid of the limiter and could make u a little more hp......... my prelude will do whats on the spedo now, but it just gives me that hanging on the road by a thread feeling so i keep it under 120

 

yeah I forgot about the mph in the ecu for vtec. Sounds like a good excuse to get a new or chipped ecu!
