ASR or Fuel Starvation?
So I've finally gotten the 92 I picked up to a point where I feel comfortable pushing it a little on some backroads and onramps, but I've started to have an issue with completely losing power on the exit of long right hand corners. I don't know enough about these cars yet to know if this is a common issue, so I thought I'd ask before pulling fuses and really diagnosing. I have ASR off when this happens and just a touch under half a tank of fuel. Maintenance throttle mid-corner isn't affected, but when I really put the pedal down off apex, the car dies on me for .5-1sec and then resumes. Does ASR turn off completely when you push the button and get the light on the info center or is there a special song and dance to get it off fully? Thanks

I suggest start by pulling OBD codes. How many miles on the odometer? |

Edit: Just pulled codes and got the typical C12 but then a bunch of --. I'm going to say it was a low fuel issue for now. Last edited by EDT; 04-07-2020 at 07:13 PM. |

Fuel starvation.
Tape pressure gauge to windshield and repeat what you did. Marty |

Re: ASR or Fuel Starvation?
You have answered your own question. C4's are known to suffer from fuel starvation on the track, IF the fuel level is low. Like you said, try it again with higher fuel level.

Also recheck the hose connections to the fuel pump. Mine came loose which can cause a similar condition to what you are having. We put new stainless clamps on and problem solved.

Re: ASR or Fuel Starvation?
Sounds to me 2 that you've located the probable issue. Rule of thumb is to keep them above a quarter tank and you'll be safe.
However, when I first read your post, I recalled a problem I had with that accordion-hose between the air filter box and the snorkel on the TB. They get warm and sometimes collapse at WOT. It is an easy DIY fix, but being new to the ZR-1, I thought you might wanna know about that quirk - should it fall flat as the tach climbs above 4500 (in my case). Welcome to the 'Brotherhood of the Beast!' Paul.
