so, here it is... runnin around on the street at 18psi.. 93 octane. only problem is my racing beat exhaust is too restrictive and cuts my boost from 18psi at 6krpm to 15psi at 7250 rpm... oh well. its fast as hell.. some dude in a z28 with a cam'd motor rev'd at me. he had no idea what he was in for =]

this is setup for iac, thermofan, etc. gets good gas milage...

1680s up top, stock primaries. walbro pump, stock fpr, s5 block, gt40 turbo..
heres a link to all mods if anyone feels the need to see

the secondary injectors are also gradually staged in in this setup. makes transition into boost very smooth.. car drives amazing.

Very nice.

 

its faast =] just wnet for another drive. im giddy like a little kid

 

for those that dont have wolf software and want to see

 

just took these out (came in the core of the s5 block).

put in 9's all around.

runnin nice and clean

 

dude charge your battery!

 

haha my charger is at work =]

 

Damm, that 2ndary injector staging is so much more refined than the V3...I'm jealous

 

its nice... i just leaned out the top 2 load bands. running a bit over 18 psi now..
weeeeeeeeee

 

and here's a picture of a datalog. from a bumpy road so load changes.. first pull was 4th gear, second was 3rd..... just one i figured id take a cap of.. normal 4th gear pull on a flat road is 11:1 dead on.. slightly under maybe

 

since i messed up the pics in the earlier post.. either way the top 2 load bars are modified (lowered a bit) since i tuned all the way up now =]

 

NYT,

what AFR do you run at the transition point (ie 0 psi)? low 13's?

 

yeah about that. My second injectors arent even on there yet and I run about 30 degrees advance also.. 25 at higher rpms

 

you running pump gas at 18 psi?

 

indeed
93 octane

 

what sort of problems were you having with the staged injectors when they "came online" too quickly??

I have mine coming slowly as well, but I start a little sooner than you did, my world fuel map never gets above7.00. I figure this might save my primaries some work.

 

saving your primaries some work will often hurt gas milage. Mine come on at like 3psi.

If yo go 100 percent to y our secondaries in one load bar, theres a time in between load bars, say 10ms on one, and 2ms on the other, that its firing the secondaries at 3 ms and the primaries at 6ms, then once it hits the bar fires the secondaries at 2ms and the primaries at 2ms.

this is because it interpolates that halfway between 0-100 is 50% secondary usage, and the value of the bars combined / 2 (dead center between load bars). You end up with a very rich spot.

 

oh and i just ran an r6 and pulled

 

well, tuned to 20 psi now... moved my split closer together (down to 4 for about 1000 rpm where i want to try and build boost a little fastder). tuned it all up too

would this map work on my car? ill be running a t78 (i want around 18-20psi on 93 octane) with new rails, stock primaries, 1680 secondaries, aeromotive fpr, full braided lines with AN fittings, dual walbros, 3 MSD 6A's, 10mm Spark wires, and a mild port job. possibly 720cc primaries (you think i need them?)

oh and ill have a wolf v4+

thanks,
kevin.

 

no it wont work. with your aftermarket fuel system you'll be flowing a different amount of fuel then me. it is never wise to just take a map off the internet and throw it in your car. if you want to use it as a base to get your car going and then tune on a dyno from there (make sure you richen it first just incase) that would be the better way to do things.

currently im running 550 primaries and 1680 secondaries stock fpr, rail, lines, and a walbro pump.

 

yea i was looking for a starting point.

anywhere you can point me to help me learn the backbone of tuning so my knowledge can grow from there? my car isnt even here, or built, nor is the wolf in my hands, but it will all be together by april/may-ish and id like to at least have a basic knowledge of tuning befor ei turn the key and blow up everything.

oooh... its kind of hard to start from nothing... id say get a tuner that knows what hes doing... you may be able to start and drive with my map, but theres a lot involved

 

Been looking over the progression of your maps. Your earlier ones had the secondary staging at a certain load and rpm. Your lastest map has just load based staging.

Any benefits to this?

I guess rpm based staging is really reduntant when you are using the 2nd's for boost only.

 

well, stock brings on the secondaries at 3800, i was kinda playing around w/ that to see if it had any merits, and it doesnt =]

the ignition maps in the maps have timing dropped a little bit so if anyone uses it there will be a bit of a safety margine just fyi. the one i posted in ultimaterx7's map is closer to what i run. ill make a new post with an exacty copy of my map soon as i get my laptop back (at my office)
