any1 w/ 90+ LB HI emp injectors around? Im lookin to not have to get a low emp box and i read that tehre is 91 lb injectors, hi emp ofcoarse, and im wondering if anyone has them on with success in tuning? I hear alot of tales about them not being able to idle for ****. How bad is that part and how tuneable is the rest of the rpm range? Thanks for the help!!

its all in the small pulse adjust, default injector pulse width, min injector pulse width, and the offset table(but sometimes you leave this alone)
http://forum.efilive.com/showthread.php?t=3032 there is a guy that might be able to help ya too. just flash a tune changing the above items i posted and make sure to put in the right IFR for the correct rating of the injectors and you should be good to go.. might have to flash it several times though

I dont have anything that big atm. Im tryin to figure out how feasable these are. I dont wanna drop the big bux for a standalone ECU or any kinda box. Obviously if its trouble to do this then i will go with a stand alone or a box to change emp. Probably a stand alone. What is the largest yall recommend on teh stock ECU? Thanks

dude. stick with gm's billion dollar computer, not unless you want to go custom.
how large injectors/ what power you lookin at puttin out?
motron 60#ers are actually 69.28# injectors at our fuel pressure. Also, RCeng.com, a sticky on this board, under the fuel and injection page can make you high impedence injectors(which is what you need)
and there are higher rating injectors for your car also that will work with the stock ECU.
its all in the tuning... obviously if you aren't looking at 96lb/hr injectors then its do-able on the stock ECU......cuz even the 96lb/hr work on the stock ECU,
so don't waste your money on a standalone fuel management system and get some injectors...

www.rceng.com (i think its this)

At the moment there are none past 75 and even those do not work as good as the 60#ers use the mototron 603 inj. they will get you past 800rwhp if you are looking for more than that use an impedance converter or a stand alone.
