i think the haltech is simpler. on the map there is a bar where it turns the secondaries on. you can move the bar around, so you can have it switch on at 0psi, 1 psi whatever you want. the injector duty cycle is relative to the height of the bar, so before the transition the bars get tall, and then after they get short because its a "bigger" injector. so the ratio thing is still there but its represented by the height of the bar. i think

jon and ito. i don't think there's any problem at all with the 550 primaries, though i could be wrong. i think its the staging. i have run 550/1600's since i put the haltech in and haven't had any problems at all. i stage the secondaries at the 12th bar. this is just over 0 boost/psi. jon, you need to hook your laptop up and download the haltech maps and let's take a look at them. you are only running the primaries only under vacuum and there's no way this should be maxing out under cruising. could you give us the settings for the main "setup" pages from your haltech and we can straighten this out in 2 minutes. honestly. and... i think this will be good for everybody on the single turbo forum. there are a lot of guys who are just getting into this and don't know how to set these up. maybe we could walk through it here? -gordon

when i have my car and my laptop back i will do that https://www.nopistons.com/forums/pub...DIR#>/wink.png

Well if you want to discuss some different setting and what they do or how they interact that would be great. I dont have a Haltech but most decent stand alones have similar settings and just understanding what some of them do would be great. I'd like to talk some about that stuff to gain a little knowledge. Who know some if it might help me out with the PFC/datalogit i have



STEPHEN

yah, we need to start some threads, gd played with my timing and now i realize how little i know :bigok:

Hey dude,



What duty cycle were your injectors running at 7000 rpm? I think going over 850cc on primaries will yield your a rough idle and shitty gas mileage.



Did you try upping the fuel pressure maybe 5% to compensate for starvation? Why not go with 850 primaries?



Mario

right now 850's are in there. it's running pretty good. going to tune it on the street with the wideband hopefully tonight!

have fun https://www.nopistons.com/forums/pub...#>/biggrin.png



mike

cool. You should be fine with that setup in regards to fuel.



Mario

i hope to get the wideband installed but it may be installed tomorrow who knows. for something so expensive it sure came in a small box HAHAHA
