On the timming screen does the load represent boost? ex: 0psi is 0 load and 15psi is 100 load?

I've been looking at the haltech E6K maps and all there timming maps are RPM x BOOST refrence. I'm trying to get a good idea for my timming map, is my example correct or not?

thanks

 

According to the RTEK2.0 online instructions: EACH 380 POINT MAPIS ARRANGED AS A LOAD VS RPM TABLE WITH EACH CELL BEING THE ACTUAL TIMING VALUE IN DEGREES.

So I reckon boost represents LOAD.

I'd wait for HENRIK or TURBO2LTR for a clearer answer. I'm just hanging out on the www net.

 

Then I wonder if 0 load is 0psi, how do I create a timming map for vacuum?

and if I change the leading timing should I do the same to the trailing eg: retard 5deg L I should the retard 5deg T?


I guess I have to do some more research?

thanks

 

Load does not equate to boost. Though load and boost are related as boost typically increases as load increases..you can still be under a lot of load, with very little boost if say your turbo wasn't spooled up yet.

If it was boost vs RPM then we would have labeled it so.

I'll let Henrik explain the details.

I will say, one of the cool things about the Rtek is the ability to log what timing cell the ECU is using. You can log the "Timing Table" parameter, listed under "Table Indexes" on the Select Param screen. This will log the RPM and load cell numbers of the cell the ECU is using for it's timing calculations at that moment in time. You can also do the same for the Fuel Correction table. If you make a log and, say, you see a spot that you're running lean, if you logged the Fuel indexes, it makes it stupid easy to see which cell you should update.

Hmm, this just gave me an idea.

 

When I say "boost" in the above statements, I really mean "manifold pressure". This could be positive (boost) or negative (vacuum).. The timing table spans the whole range of possible manifold pressures, not just boost.

Sorry for the confusion.

 

Thanks, is there a simple way to make a timing map that would be safer then the stock map? without being able to have the whole stock map in front of me, I'm having trouble picturing it and where the heavy load points are.

thanks for the info
