I live in AZ and I’m about to Turbo the car, But I do a lot of distance driving which takes me to extreme elevations, up to 6000+ or sea level. I worry that the car tuned to the 5000 < > elevation were I live at will have problems once I drive to sea level. There is little Oxygen at this altitude and I don’t want to lean out once I get back to say California or Nevada. How practical would it be to load different maps for different altitudes, and can I do this with the e-01? Bear in mind this is my first Turbo car. In fact, the turbo is still in the mail.

and yes I did a search but I still dont have a full answer

if this is a stupid ???? wath the hell I'm a new B

 

It's not a stupid question at all, and you should get some good responses pretty soon.

I didn't think the e-01 loaded such maps but instead it was done in your eManage system. From dealing with my eManage it was pretty difficult to load different maps and switch between the two. Some people on here have had more success with the eManage and can probably answer that better.

 

The e01 does (suposedly) have the ability to save and load different MAPs. But, there have been issues with this functionality. GReddy may have fixed them, but I'm not aware of it. Basically, my own experience was that any time I used the e01 to program the eManage, the e01 would F-up some of the settings. Others on this forum have had similar issues.

As far as the AFR and altitude relationship, I think the answer is somewhat dependent on how you have the eManage configured. The stock MAF will, of course, be able to sense that the air coming in is more dense as you decrease altitude. If you have the emanage configured as Greddy sent it (a large portion of the fuel added is added as a % of the PCM output), then the effects of altitude will be at least partially compensated for. The PCM would call for more fuel since the air is more dense, and the eManage would add its % on top of that.

If you have the emanage configured as I did it, (100% of the fuel added with no PCM input at all) then you are probably going to have more of an issue with changing altitude. Since under this configuration the fuel added is only dependent on boost pressure and not mass flow rate, then you'll probably have a leaner AFR as you decrease altitude.

 

If your trips to the higher altitudes are just for short durations, tune your car at your lower altitude and then you'll go rich when you go higher. You'll just have less power when you're higher up.

If you have a laptop with you both the emanage and Interceptor can have new maps loaded into them as needed. The Interceptor is a little easier though as you can save up to 4 maps in the provided dongle and then switch between them.

With the Interceptor you can hook up a switch and when that switch is depressed you can add or subtract a certain percentage of fuel across the board. So you could take advantage of that as well.

 

Dang, the plot thickens……so from all this I figure that Mad dogs setup is not my best option, (Maybe) How hard is it to load maps from the laptop to the Emanage , I live at 5000 feet elevation and I run pig rich as is. The interceptor does sound badass but it’s expensive as hell. Is it really worth it? My car is a 2005 and from all I have read the Emanage doesn’t like my cars software to much.

I have the opposite problem, I live at high elevation if I tune for my town when I drive to lower elevations I will be way to lean.

 

Oh and another thing, If the e-01 cant reliably store and load maps is there another boost controller that can …lets say HKS or Apexi, like I said I’m at a loss on this, should I just get an interceptor and a Apex boost controller and be done whit it? If the e-01 can’t really program the Piggyback why even get it?

 

To just answer in very basic form, which is nearly impossible for me, don't worry about it. The ecu will compensate for altitude. Yes you will lose some power as you go up but your engine will be running at the proper a/f ratio the whole time. A map has many different load, rpm, and pressure points to compensate for all situations. A map is not a 2D thing. It's 3D.

 

Even if I run the same set up as Mad dog? And that is the badest avatar dude I just about spat my oatmeal first time I saw it.

 

NA PCM MAPS - yes.
Aftermarket TURBO MAPS - no.

 

So basically get the Interceptor and boost controller and have a lap top with maps...damit!!!! I’m going to get drunk TTL
