Instead of creating a new thread i have a question i have two ecu's

#1) The original ecu that came with the car works fine the car idles well and drives very responsive "BUT" transmission bounces from 3rd gear and 4th gear and well never really goes into 4th gear .

#2) This Ecu is from my first sc and the car goes into all gears "BUT" doesn't always feel so responsive in throttle and when at a light the car idles super low even after adjusting the throttle cable

What Can It Be?

Anybody have a clue i need answers.

Default Surging idle

I recently rebuilt my computer cus it went bad but now I have a high surging idle from 1500 - 2000 rpm repitively if it's in park or neutral but if it's in drive it'll stay at a constant 1400 and if you try to drive it'll sputter and stall out if you try to give it much gas..... Has anybody else experienced this? Anyone know what it can be?
