What did you do to your Gen7 today?

What are the benefits of an overdrive pulley?

For the alternator, he would be able to spin it at the same speed as an OEM pulley combo with and underprice pulley on the crank.

^ he beat me to it

produce more amperage/voltage at any given RPM to counteract the effects of the underdrive pulley.

So lets say that you have a UR underdrive pulley. It bring voltage down to 13.6v, with a overdrive pulley you can bump the voltage back up to 14.4v and run larger system.

Got the estimate for the rest of the body work. It's not pretty.  but It's happening! Bringing it in as early as March depending on Warren's schedule. He's going to keep it for 3 weeks.  I can't wait!

Ran a couple scans today. I think I'm running a little rich at startup. Gotta investigate this weekend. Also not sure why I'm getting an incomplete for my catalyst in emissions readiness if the check is turned off. This i gotta find soon because emissions testing has to be done by end of next month.

Its the tune.
Ask Dom to help you out with the part throttle tuning. We are currently working on mine since it was smelling like gasoline when I was parked, but he fixed that right up. Going to try to get max economy and reliability/power all at once.

Did some more work on getting my throttle body to close properly when driving part throttle.  I believe it's mostly figured out.  I also relocated my IACV closer to my inlet vacuum fitting.

I did mention it to him when he checked in to see if i was ready to start tuning again.  He said to see what Paul had to say first n let him know. Were you having trouble starting sometimes after sitting for a few minutes? That's my issue. It won't start unless i give it gas n hold it above idle for a few seconds then all is fine. It doesn't do it all the time either. So in conjunction with the map Paul wanted me to check the injectors for leak after priming a few times to see if one's getting stuck open. Also the pressure seems to drop pretty quick, 60 to 40psi, as the car warms up.

[thisaznboi88]

For my problem it only happens once in a while. I try to start the car and it takes a few extra seconds of tuning it over before it starts on his own power. It feels like it about to die before it starts, but starts right up. So my thought was that it was getting boarderline flooded. This only happens after I drive it and park it for a little. Doesn't happen from a cold start.

new tune seems to be working just fine though. The car doesn't smells like fuel when i park the car anymore.

[Rich01]

Exactly what mine is doing except i won't keep it turning over for longer than normal. If it doesn't start normal, i wait and then start it with a little throttle and hold it for a few seconds until it can idle on it's own. I'll get a log over to Dom but I'll still check the injectors also just in case

[thisaznboi88]

^ yeah definitely talk to him after you talk to Paul about the fuel pressure dropping issue.

I am pretty sure its the tune need to be adjusted for part throttle. I was getting <12.6 AFR during load. I have an AEM UEGO so I see it dips into the green instead of yellow area. After adjustment its around 13's and normalizes to 14.7-15.0 when the load is removed. Still working on the mapping, but MPG has definitely has gone up after the last few revision. No more 10-15mpg in the city or 20.5mpg mixed

I would also check your oil often since running rich dilutes the oil.

[Rich01]

Yeah, I'll get him a log this weekend when i get back then I'll change the oil because i the oil n filet for the 2nd oil change ready to go. And yes i would occasionally get into the 12s on my wideband also but i rarely go above 3k if at all since I'm still breaking in. Thanks Ken.

Took my old leather steering wheel cover off. Feels weird. New one should be here today!

[Nit3h4wk C0uP3]

....and it was! Just spent an hour sewing waxed thread through a leather steering wheel cover lol

and you didn't post a single picture? Shame on you!
