Installed my Piggy back after my car had been sitting for a long time and really? really road race? Now my revs bounce and i cannot rev over 4k among other engine problems and it eatting threw gas. sounds like the rev limiter kicks in. im going to cut the battery for a little while tomorrow to try and restart my whole system but if that doesn't work im going to cut out the piggy back. Garbage.

BTW- i have a Piggy Back ECU from RRM for sale.
price: 1 big headake plus shipping.

 

No offense or anything, trust me I'm the first to say RRM's products are garbage, but it sounds like you may have installed it wrong. Like spliced the wrong wires or something. I don't know the piggy back is all that great een when working, but if you decided to keep it, throw up some pics and what not and someone can check if it's the install or the product itself causing probs.

 

Ill get some pics tomorrow before i rape it out of my car because i have a 360 mile trip saturday. maybe i did, maybe not, as is i would rather not deal with the head/heart ake because i deploy april 1st.

 

I had exactly the same problem and it turned out that one of the wires was connected the wrong way.
