Veteran Posts: 267 Location: Sydney | Hi all The one Ive circled is the one that was in my car, whether original or not I dont know, but quite likely it was. Edited by 1coolbanana 2018-11-12 1:34 AM | ||

Veteran Posts: 267 Location: Sydney | FYI I cant even imagine what this curve could possibly work with! Ive kept the original distributor as is unmodified, I like to keep all the original parts unmolested and will use the new one with original curve. I can only guess that my poor running problems will be over. Will test drive tonight :-) | ||

Extreme Veteran Posts: 371 | What kind of distributor, make. The mopar performance distributor is really not suitable for day to day driving. It takes some hard runs down the strip a few times accoring to the mopar engine bible. Also mopar states that in most cases the stock distributor is more than capable of delivering the need spark. Using the gold ignition box is not needed either according to them, unless your engine regually hits say 6,000 rpm's. | ||

Expert Posts: 2264 Location: McComb, Mississippi | Not trying to steal this thread, but does anyone here check/ adjust advance curves for others? | ||

Extreme Veteran Posts: 371 | I have an old Stewart/Warner roll around shop engine analyzer and it does check curves. It's the old osilascope thing with buttons and it still works even the timing light. I keep it because all but 2 of our vehicles can be hooked up to it. | ||

Expert Posts: 3575 Location: Netherlands | I've learned hardly anyone 'can be bothered' with advance curves because most people simply don't want to learn to tune it better than the factory's compromised settings (which needed to work in all climates, so leaves a lot on the table). Once you start working with digital ignition systems you can actually "see" (even in 3D) what an advance curve is, especially with a vacuum advance in the mix. | ||

Once you start working with digital ignition systems you can actually "see" (even in 3D) what an advance curve is, especially with a vacuum advance in the mix. Would be great to get a properly tuned curve. Digital makes things very easy. I modify curves on EFI setups and it really makes things easy (motorcycles) Also makes it easy to mess up too :-) Edited by 1coolbanana 2018-11-18 3:16 PM | ||

Id be very interested to see what the curve was like... | ||

Expert Posts: 3575 Location: Netherlands | I've installed a MegaSquirt ECU in my dailydriven '73 Dart. Currently controlling ignition only at the moment but will be incorporating fuel-control later on as well. I've been tinkering with the timing map for a number of months during the daily commutes to get the most out of it. The engine runs (on LPG) like a champ in just about all the RPM-ranges. | ||

Extreme Veteran Posts: 371 | Ok banana I checked the link you put in. Sorry but I have seen so many issues with "performance" items used on non race cars. They look so very cool and like they could launch link a rocket, but are gutless wonders. I simply rebuild if I can the OE distributors, sorry I am old school. Like I said I've the blaster coils and super coils, hot billet aluminium distributors on engines that simply are never raced, but people think "hey if for a dragster it'll work me". I have no problem using single or dual points either. If your running 12.0 compression and burning 150 octane go for gold, but other wise money is better spent. My old 354 baby hemi has it's original ignitionm rebuilt, and it purs like kitten and is more than happy running at 100mph all day long. And knock performance is far worse than the real mckoys. Not sure but if you want performance, Summit or Jegs don't deliver to you there or what? Or they just don't have what you need? | ||

Veteran Posts: 267 Location: Sydney | Im not chasing "performance", Im chasing reliability and making it as good as it can be. My preference is with parts that are readily available in this country, which isnt much. The advance curve is back to standard, it now runs great after rejetting the standard Carter for the new manifold and starts fist kick and is smooth as can be. I have no interest in doing 100 mph all day, or anytime really. Buying from the US is just too hard, too time consuming, too expensive and just takes too long and unless there is no choice, I try to avoid that. Edited by 1coolbanana 2018-11-22 3:55 PM | ||
