Bump Box from XFI

Taking a long shot here. What settings do you have to creep the car to the second stage light in (mil) seconds rather than having the car jump like a grasshopper?
If not I will continue tuning.

Thanks
Joe

I have these values and tested it once. It seemed to work smooth but is was tested a few years ago....

Let me know how it works because I haven't used mine much but thought it worked when I tried it.

Is this on a 200r4??? I really need to get my creep to simply move at this point. I can't find anyone with it functioning on s 200.

I tested again this morning for the first time in probably a couple years and it seems to work acceptably. It moves the car slowly without any violent jerking but it does have a slight stutter feel like the DC could be reduced a little bit from 7 to 5. I have not retested this yet with this new setting but I suspect it should get even better. Even at these initial settings it should be good and I'm just being overly critical over the feel.

you will find that if you raise the boost or launch RPM you will have to readjust.

what kind of relay are you using? I've read that a solid state relay is best but the only solid state DC relay I've found locally is rated for 5 amps and I tested my trans brake solenoid and it's drawing 5.5 amps. Has anybody used a standard Bosch type relay? The help menu states a mechanical relay can be used but at a reduced range of control.

I'm using a solid state relay. FAST sells them on there website and are a little pricey compared to a mechanical relay. If you look around in Newark, digikey or Mouser I'm sure you can find something more economical.

I found this one on Digikey and ordered it. Hope it works! On off time is .5ms. https://www.digikey.ca/product-detail/en/ESR10-NC2A4HB-00-D1-10A/302-1464-ND/6490743

Hi Alan
Well better late than never... I still can't get it to work, and the funny thing is that it did before. I will play around with it again. For now I am using the foot brake to stage

I know this is an old post but I’m looking to do a 200 trans brake and the creep function on the xfi . My question is what trans brake are you using
