Throttle boggs out of first gear, what could it be?
Hello,
I've recently bought a 1994 RX7 from allrotor93. the only mods done are a koyo rad, AST delete, HKS twin power. I noticed trying to get out of first gear the car bogs down and I either have to compensate and give more gas which makes me basically burn out, or I stall out. I figured out this system where I rev it once to get the RPM's up then start off with the clutch but I really don't want to have to do that all the time. This is my first rotary powered car and I'm trying to learn as much as I can.
Any suggestions are appreciated.
Thanks,
Alex

Does it still do it if you disconnect the HKS? If that doesn't do it then I would probably start looking for intake leaks or possibly a cracked hose going to a sensor like the MAP sensor. Seems like your car behaves like it has a tuning issue similar to what a carb would do if the accelerator pump wasn't working. Since you have stock ecu I would look for anything else that could affect air/fuel mix. Sounds like it catches back up and runs well after the initial bog, that's why I think small leak like the line to the MAP causing a delayed response. Also check the TPS, you should be able to find instructions on setting that somewhere on the forum.

Update: I tried the easiest fix, which was reset the ecu but that didn't work. I then removed the twin power and it completely fixed the problem. The only thing I can think is since my car is basically stock I dont have the supporting mods to justify the extra spark. Thats just my guess...
I now have a smooth idle and no hesitation out of first gear.
Thanks for the help.
