For some reason the Cobra .bins seem to use the same slopes. I started my X3Z tune this way and it seemed pretty close, but I did need to make some adjustments. That is about all the detail I can offer on that. Keep in mind that the initial slope settings are going to be rough anyway. KAMRF based adjustments will probably need to be made regardless. jason |

Re: vristang.... question about your post on stangnet
yeah I knew that the x3z OEM settings were that way. Just wondered if you had confirmed that all x3z injector slopes should be set that way when modifying

Re: vristang.... question about your post on stangnet
Also, I'm curious as to why you would put the fuel pump size stipulation in there.

Re: vristang.... question about your post on stangnet
The pump thing (I've seen that recommended somewhere else on the web - I think that's where he got that from) may be related to how I've had to cut way back on my fuel up top after installing my BAP. OTOH, I am now wondering if they were referencing a returnless system WRT the pump sizing? Anyway, these are the thoughts that popped into my head reading this.

Re: vristang.... question about your post on stangnet
I just pulled up the ZAO .bin for the 95 Cobra R.
Both slopes are set to 24lb. I just looked at the Tweecer manual, and that said nothing about setting the slopes the same. Does anyone know what size fuel pumps the 93 Cobra and 95 Cobra R came with? jason

Re: vristang.... question about your post on stangnet
Don't know about the 95 r but the 93 came with the same pump as the standard 5.0's (88lph)

Re: vristang.... question about your post on stangnet
Well I guess the pump stipulation didn't come from the Cobras then.
I fear that I won't be able to quote a source, since I didn't start keeping track of most info until a few weeks into my research. I am glad to hear Cougar5.0 say that he has seen this mentioned before. If I am crazy then atleast I'm not crazy and alone. I am using the X3Z, 30lb injectors, and have both slopes set to 30.5. My KAMRFs seem happy with that. I'll look some more and see what I can find. Something I had not considered until just now is the way the A9* series uses the Injector Breakpoint. Maybe this has something to do with it? jason

Re: vristang.... question about your post on stangnet
Also, I have heard mention that when using larger fuel pumps (190 and 255lph) the stock regulator can have trouble maintaining a fuel pressure setting.
The thought is that the pumps are too strong for the regulator to maintain control. This may explain the fuel pump recommendation. jason EDIT; Qwksnke - Are you using a Tweecer with your x3z?
