Well, I had some problems back in january with the PB and I shipped it in and had it reflashed. Well I got it back friday and installed it. I feel like the same thing is wrong. I followed all the instructions, made sure the wires were making connections, but I got the same results. #1) the car sounds cammed, more like a harley than a car. The engine is running very choppy. My exhaust is shaking around and hitting my bumber at all speeds. The idle is a little rough, but so is the whole ride. The roughness never goes away.#2) The car is actually slower. It actually feels restricted, like it has something holding it back. The sound it makes when given full throttle is not a pretty one. I can't really describe how it feels though. The car doesn't run well, and its actually running slower. I have installed the PB 4 times now and had the same results. I just don't know whats wrong. Any help is much appericiated. Please help!

 

Check your plugs and plug wires. Make sure your plug wires are connected properly and on the proper cylinder. We hooked up the wires wrong once and the engine movement looked like the movement from an old v8. If you have a cam, take a picture of your connections and post it here.

 

I assume your car was running fine without the pb, so then the problem either has to be with your wiring or the pb itself.
How are the wires connected did you solder them?

 

I have done the PB connections 4 different times. I haven't soldered because I was going to wait to see if it worked before I did that. I have used connectors pieces to make the connections and Im 100% sure good connections were made. Since I have sent the PB in already, Im thinking it should be working right. I will check my plugs and wires and Ill post in a bit.

Did you want a picture of my plugs or my PB connections?

 

Both if possible.

 

i had this exact same problem with my piggyback, the only way i got it fixed is when i actually took it in to road race and had them tweek it with the splitsec program

 

taking it in to road race would be a bit too hard for me. I'm in Houston, Tx. Maybe a spring break road trip is in order. But I'm going to check my plugs and then re-install the PB to see if I have any luck.

 

ha yeah, i live a 40 minutes away and i think its a pain in the ***, well if you consider getting the splitsecond program maybe someone who has what they think to be a good map can send it to you and you could use it

 

if you go that route... make sure you get a map made for Piggy Ver2. I've got my own map, but for ver 1 so I'm no help to you in that scenario. But then again, I read today that the idle fix wasn't in the map, but in output settings. No matter what map you use, the settings from that map aren't used in the idle fuel trim. So the map is not the issue. Output settings as I read this morning makes a lot of sens.

 

Alright. Thanks for all the help. I checked the plugs and the plug wires. I guess that is what it is because it's working now. I've only been on it about 20 miles so far and I've noticed a little power increase. So I'm hoping when I get to around 100 miles I'll notice it all. Thanks for all the help!

 

did you disconnect your battery for a couple min, the change might need a reset.
