Version 10 of my ECU Explorer templates are now available!

[Mark P]

Please check my webpage for the complete details:

Please use all new files if using v10. Once you've used these, please let me know how it goes. I've made some minor last minute changes and haven't completely tested all the files together from start to finish.

Here are some highlights:

************************************************** ************

New for Version 10 (9/1/05)

Group File:
- I added AcceleratorPedalPosition. This enables the macro to grab data based on the Pedal position, and not the Throttle Body position. As such, the macro to grab data even when the Throttle Body is not fully open (low RPMs, throttle cut, etc).
- I added EGTbank1OXS and EGTbank2OXS. These show the Exhaust Gas Temperatures at the primary O2 sensors in the downpipes. These can be useful to get an idea of temperatures at this location when the True EGTs are not high enough to register on the real EGT sensors (which are logged as EGTbank1 and EGTbank2).
- I added OXSVoltS1B1 and OXSVoltS1B2. These show your O2 Voltages which can indicate how rich or lean your engine is actually running. Desired A/F is what the car is trying to obtain (prior to any tweaking by Lemmiwinks, V-Tune, etc), where as O2V show what is actually occuring.
- I removed IgnitionTimingCyl1-IgnitionTimingCyl6. These were taking up 6 spots that were more useful for other variables. Also, the combination of all 6 of these is already noted in IgnitionTimingAngleOverall.
- I rearranged the variables in the Group File as well so they were better organized, and better match the order of graphs

Data Prep:
- The data is now being grabbed based on Accelerator Pedal Position being at >90%. This will allow proper grabbing of data even if throttle cut occurrs.
- The "Color Legend" Excel tab in grab_data_macro_v10.xls documents the various color coding. This is documented below in the "Color Coding" section as well.

Graphing:
- I rearranged some of the graphs to put them in more useful/logical order.
- I added graphs for the new variables listed above that were added to the Group File.
- I created an Automatic FATS Calculator. No longer do you have to cut/paste data into the previous calculator. Now the data is entered automatically and there is one on each tab in the single-gear template (4runs_compare_graph_v10.xls)
- I created an Automatic 0-60 MPH Calculator. On the multi-gear / timebased template (2runs_timebased_graph_v10.xls), there is a 0-60 Calculator on each tab.

Note: Due to the various changes, mixing versions of files will not work. Please download all new files below.

************************************************** ************

Automatic FATS Calculator
On each of the single-gear pull pages, there is an automatic FATS calculator (manual version here). If the data you paste is for a 3rd gear pull and contains data extending from 4200 to 6500 RPMs, it will calculate the exact time it took to perform this task. There is a graph (see below) in addition to the raw number. Here is the calculator, which is automatically filled out:

Each page has a calculator:


Each page has a corresponding graph:


The Compare page has the overlayed graphs and a summary table:



************************************************** ************


Automatic 0-60 MPH calculator
On each timebased multi-gear tab, there is an automatic calculator to determine your 0-60 mph speed. There's also a corresponding graph.

Here is the calculator


And each page gets a graph. I added RPMs to this graph as well so people could correlate the two (esp the shift to 3rd near 60mph). Also note I allow the primary axis to auto-scale with the time it takes for each car. I didn't want the RPM data to end up directly under the time data, so I forced the secondary scale to 1000-10,000. This will keep RPM lower on the graph to avoid intereference. Likewise I used a thin line for graphing RPM.:



************************************************** ************


As noted above, because the new grab_data macro now takes it's data based on Accelerator Position instead of Throttle Body position, the new macro will grab the data even when throttle cut occurs, as shown here:

Here's the graphs for O2V which is now included:

when I get ECUx running again I'll be sure to try this out.

winter washer fluid or 50/50 in your Aquamist?

I've used washer fluid sometimes and other times I used the water we have at work, which is something like "reverse osmosis and active carbon filtering"

It seemed the water did better cooling, and the washer fluid added a bit more fuel. I forget what's in there now, I haven't used it in a while.
