So I have 502s with EST distributors. I need to run 10-15 degrees at idle adn 36 degrees total advance with a mild cam. They idle at 800 RPM.
Since EST have only 10 degrees of actual advance above 800 rpm, their is no way on earth they will tolerate 26 degrees at idle and pulling on plane. This seems like the dumbest module on earth. Can I get another module that has 20 degree or so of advance that is a normal curve? this is a real problem. I wonder if everyone just runs 26 total timing, used a ton of gas on their overheating motors that were down 20% on power and thought it was awesome????

well many run dist locked at 30+ so 26 at idle will not cause a issue, EST also have about 20 deg in the marine ones, set the total around 32 and let the base fall wherever, sounds like you have other issues to me.

I've used the EST dist with Crane (now Daytona) boxes.

EST have 20 degrees of advance but.... you 10 of them before 800 rpm (seriously).

Most guys have hot cams running locked timing so cylinder pressures are super low. Mild cams can really pack cylinders at low rpms as they have no reversion.

Daytonas??

My son's AT we just installed the Daytona boxes on, seem to work well, I had used their LS box on a carbed race car before and it worked well. I also tried playing with EST's seems they work well in more stock apps than performance ones, my Gibson w/454 crusaders used them OEM, they did have 20 deg in those, you had a plug you pulled apart, flipped over to set base timing, then flipped back to run. On that 8 deg initial gave you 28 total. I experimented with a HP one but it was designed to work with a ecm, so failed on that one.

I thought you converted your boat to Holley EFI, not using its timing control feature?

if I recall correctly daytona Sensor EST distributor is made in china does anyone have one of those ? And how is that quality ? I do know Sierra EST distributor and related parts comes from China as well and is pure junk chit
