So after installing my cams I'm seeing an issue when trying to go WOT. The car hit's what feels like fuel cut and falls on it's face in 3rd gear. The log shows the load drop immediately but everything else looks fine when that happens. I can't attach the log (says it's too big). so I'll put it on 4shared here - http://www.4shared.com/file/m3VAX9Q4...5_071226.html#, if you focus in on the first pull (I don't know how to trim logs with this software) you'll see where the load falls on it's face but everything else keeps going.
I'm not getting enough knock to suspect that. What I am suspecting is the CAS? Could a faulty CAS cause this?

**Also, I'm using Tephra V7.

 

Can't see the log cause I'm currently at work, but does it feel like a spark blow out? What are your plugs gapped to and what boost are you running?

 

This is normal...... get your car tuned. Judging by your mod list you should know swapping cams can cause all sorts of driveability issues untill you tune.

 

You do have your fuel cut load set high enough correct?

 

Have to signup to download the file, which I'm not bothering with. Change the extension from .csv to .txt and upload it here. We'll change it back to .csv to open it.

Sounds like fuel cut though.

 

I'm running 26 psi, and plugs are gapped to .024 (plus I have the sun auto ignition system with the spoolin up COP. so I don't think it's spark blowout.

Absolutely, but that's the problem. I'm trying to tune it but getting this cutout. I can't see anything in the log that explains it so that's why I figured it might be mechanical (the CAS).


I didn't know you had to sign up to download from there. I'll do this and see if it helps. Thanks for the idea.

 

can't upload the file here either, file is too large. ugh..

 

Trim it down so that it's just the pull.

Alternatively, put it in a .zip archive.

 

I'd love to trim it down, how do you do that with evoscan though?

 

Open it in excel then delete the unnecessary rows and save

I think you might have figured it out. In the settings you have 2 choices for fuel cut modifier (?). Mine was set to 1 (maybe the default with tephra 7), so I set it to 2 and didn't really have a chance to get on it to redline, but I got on it a little and didn't see any cutout. I'll try it again tomorrow on the same stretch of road I had issues on this morning.

Thanks for the suggestion!!

 

You need to set it to like 400 at first, make a couple pulls and make sure your boosting how much you want, and then go back and look at the logs and set your fuel cut so that you have just a little wiggle room for your load to go up a little.
IE: if you hit 300 load in 4th gear, set it to like 315-320.

the reason for load1 and load2 in the tephra rom is because load1 will only go up to like 318 or something so if your load is going over that you will have to set it to load2 and use that table and load1 becomes irrelevant.

 

Wow, I never knew about this. I need to re-visit the manual!! Thanks for taking the time to explain that!

 

I was also having an issue with load dropping to 0 in the middle of a pull. Rescaled my limit table and all was well. There is the timer which I think is set to 20 seconds from tephra? That allows you to go over your limit for that amount of time. As already stated you'll need to adjust your table once you switch to x2 cut as I believe its at like 600 from tephra.
