Maps

[donny_b]

How about sharing some Maps... I have a very basic map but I would love to experiment and learn. TTP how about a tutorial on how to make small adjustments to out Maps? Thanks guys.

First of all, do you have the equipment to safely measure afr and ignition timing advance?

There is NO WAY to customize a tune without the basic datalogging equipment such as a Zeitronix ZT2 and obdII scantool able to record or display data.

OK, noted....just wishful thinking..

Yeah, so the peeps in other threads on other forums saying we can easily swap maps, custom tune, etc. really mean= Go to a custom, knowledgeable tuning shop with an AWD dyno, take them the Zchip tuning software, and hope they know what they're doing with this new product... W/O the diagnostic equipment/dyno, the average person really can't custom tune their own car.

You can self tune the car, however like any engine, you need to monitor how your changes are affecting the engine.

We seem to have only reached the tip of the iceberg with the Evo X guys.

Many Evo 7-8-9 owners have a complete wideband setup at the least whether Zeitroinix, AEM, PLX etc.

You need a wideband to record the AFR when you are doing pulls on the road so you can stop the recorder, review the AFR by RPM and make adjustments at every 100rpms.

Its no more difficult than the Evo 8-9, however there are many Evo X owners that are "newer" to this type of hands on motorsport.

In due time we will see more interested parties become more willing and comfortable in making adjustments themselves.

Cool. Perhaps in the meantime, TTP could post a few custom base maps with full descriptions & estimated gain with various light mods., so at least for now we could download a few a play around with this whole ASC mess.

Lallen3 is right, it would be nice to see some maps in the "maps" thread.

[TTP Engineering]

All ZChip "buyers" thus far have their basemaps unlocked so they can be viewed by the owners of the zchips.

Do you mean online or by extracting the map & sharing it off of the actual chip? thx

[TTP Engineering]

With the software download, you are able to SEE your own map.

Tuner maps are locked however and are encrypted.

[lallen3]

Does this mean swapping maps isn't possible?

[TTP Engineering]

Does this mean swapping maps isn't possible?

No, there are tuner maps and unlocked maps. All maps sent on batch 1 are unlocked maps in order to jumpstart the understanding and self custom tuning ability.

Here's my base map. I'm located in Anchorage, AK...sea-level, 90oct+torco, let's see some others. Unfortunately, I haven't been able to log any runs due to the snow. I can't wait to get started.:D

Dumb question, but i have to verify. If input voltage is 5.0v and adjustment is -35, that indicates a .35v reduction in output or 35% reduction in output?

No this is not correct. It is not measured in percentages.

[tsitalon1]

No this is not correct. It is not measured in percentages.

Ok.. so in the example above it would be a .35v reduction correct?

[Zeitronix]

-1 is roughly -0.02V so -35 is roughly -0.7V

[tsitalon1]

-1 is roughly -0.02V so -35 is roughly -0.7V

Ok..so i guess this is simply a guessing game requiring a WB02. Did I miss some post explaining what all the values mean?

I'm am used to using dsmlink to reduce or add fuel/timing through percentage differences. I might not be clear right now, but I am trying to mentally correlate what the real world change would be to AFR by changing the values. It seems like it's going to be somewhat of a guessing game by slowly changing the values and monitoring the AFR VERY VERY carefully.

[tsitalon1]

Do we have a reference for stock output of the MAP sensor referencing boost?

Example 5psi = 2.68v

[Zeitronix]

14.7 PSI _ABSOLUTE_PRESSURE_ is about 1.4V

Adjust in small increments carefully monitoring wideband AFR and timing.

Ok.. so thats what I thought, we don't have a table reference. Thanks!

It was one of the things we plan on testing but basically using a leak tester and zeitronix with MAP sensor + logging voltage to AUX1 user input to the zeitronix and sweeping the pressure upward to max range of 5.00vdc, one can make a scale.

I hope once we have this established, zeitronix can correlate it to display on the zchip tuner software. One would be able to determine boost this way. :)

[Zeitronix]

We do not have exact specs of the 3 BAR MAP sensor. Not sure if it's temperature compensated like our 3.5 BAR MAP but at this point it appears to be:
0.16V at -24 inHg
1.4V at 0 PSI
3.8V at 24 PSI

Those are rough numbers based on initial testing. We would need to bench test several 3 BAR sensors in lab conditions to see how repeatable those numbers are. But it's a good reference start.

For everyone in the South here's the Mail-in Tune I got.
I specified 40ft above sea level and a AGP cold air intake. It'd be nice to see some more maps at similar altitudes.

Thanks,
