Help with Tuning please

[Dzaster]

So I got the turbo installed and running today. I took it for a drive around the block just to get some idea of what things are like. I found that I'm getting excessively lean once boost starts.

This is the log file that is put out by that EmanageTools 3rd party software. It logs the AFR as well. I realize that some of the other features are missing, but I just wanted to try it.

Couple questions:

1) I don't have the stock MAP setup to be clamped by the EMB. Should I and what would be a good setting? 5V? I have the stock MAP line vented to atmosphere when under boost.

2) Also, how the heck do I go about correcting the lean situation under boost. I understand that I'll have to alter the Additional Injector Map, but I'm not certain as to how I come up with the correct numbers

Clamp the map voltage at 4.5V. If you have the injection harness installed log your injector duty cycles around the same points where it leaned out at 1lb. then increase your injection by say 2% to start with. The drop in afr is becuase the system is switching from the oem map to the greddy map.

I clamped it as you suggested at 4.5 and it seems to have done well. However, I was advised, that based on my datalog that I should have the stock MAP clamped at 0 (psi/vac). For my car it is 3.7 so I have changed the value and am going to try it.

[Accord2nrz]

ideally that is the case, but if your going to do that you need to find a way convert the psi it reads to voltage so you can clamp it at exactly 0v.

I used that conversion chart that someone posted up here. I actually printed it up to have with me too.

I went and tried some tuning today and never got lean on the gauge. One logged pull had nice AFR numbers--8psi had 11.5AFR. The EGT's also stayed within safe temps. I did a 1st, 2nd, 3rd pull, pulled over and inspected #1 spark plug. This is what it looked like. Its a crap pic(phone cam) as I forgot my dedicated cam.

Because we have only 92 gas here I am using a bottle of octane booster per fill so the brown is obviously from that. Anybody see any problems with using octane booster long term? I've tried the NOS and also have a bottle of Lucas octane booster.

What's the purpose of the acceleration map?

[Accord2nrz]

For tuning based on throttle position during acceleration.

i apologize for the newbie question but how do you get your values on excel like that? or did you simply go through and input each value manually?

[Accord2nrz]

You'll have to down emanage tools. It's a 3rd party software that produces the excel log file.

[mijos87]

i got the emanage tools and have my afr gauge spliced into the yellow wire (which is not used) which would be for a second maf had my car have one. no i cannot seem to get the emanage tools to work. it either freezes or says it cannot connect to the emanage. am i supposed to run it along with the emange support tool? or seperatly? am i supposed to do sometyhing before opening up the app?

[Accord2nrz]

Are your com port settings all set right? Open your support and see if it's connecting to the emb, if not then I suggest you adjust your com port settings. If one connects the other should too.

[mijos87]

thats the part that was driving me crazy! lol they are booth set to com port 4 the emanage support tool connects but not the emanage tool:confused:

[Accord2nrz]

are you running the program as an administrator?

[Dzaster]

You have to run one software or the other. YOu can't run both. Also be sure to go through the settings and make sure you have everything set right in the emanagetools. Especially the range of voltage your particular wideband uses.
