Hey guys I got a wolf3d wired up in my car. I've only had it running for about a week and last night it got real cold. Its comming up as -1 C on my wolf3d for coolant temp. Yesterday I had it running perfect at idle, pulling about 55kPa vacuum. Then today I go and try to start the car and nope, almost starts but doesnt. I start messing with the coolant temp compansion values and get it running by holding the gas pedal. I had it at about 1500rpms by holding the gas and it sounded like ****, was also making a ticking noise.... So I look at my vacuum and its only at 20kPa...

So after about 3 min running by holding the gas the car dies. I go to start it again and nothing wont even try. By then the coolant temp was upto about 22 C. While cranking I was only pulling in 2-3kPa vacuum, but just yesterday it was pulling 20kPa while doing the same thing.

No I didnt blow the engine yesterday, because I started it up lastnight and let it idle for like a min and shut it off... It started great and held idle perfect.

Does anyone know what could be causing this problem?

 

Try increasing your ignition coolant correction maps buy about +5 degrees at anything 0C or colder. Ramping down to zero correction near operating temp.

 

Slightly advanced timing will help keep the rotors spinning. Also, when its colder out, increasing the START IGNITION TIMING will help turn the engine over faster.

My base START IGNITION TIMING is 15 BTDC...

 

Nah that didnt work. Any clue why my vacuum is so low?
