No, I am connecting thru hand held, laptop-hand held-ecu. Only using the hand held for connection to ecu and for gauges. When you use the procal on the laptop you don't use the hand held for programming anymore, only for connection to ecu.

only after you do the newest update , then yes in setup menu at the bottom after you've picked cam, engine size, reluctor etc it'll ask na or super on handheld.

Even then I wouldn't run boost to this system without correcting the 1-4cam afr chart/big spark table/turning returnless fuel option off in procal

The Driver is in the Fitech software install folder, after installing the Procal SW you then will find a drivers folder in the fitech folder. It is in c:\program files (x86)\fitech. This KLINE driver is the gateway from your laptop thru the handheld to the ecu. After installing drivers connect your laptop to handheld connected to ecu with key on. Your handheld will give you 3 choices select Kline this opens the door to the ecu. On laptop top left select connect and it should show connected at the top. Click on gauges and your gauges at the bottom should be active. Good luck.

I doubt the Fitech ECM cares if an alternator is connected or not. What alternator do you have?

watevadunno

my alternator is the same as the ls1 GTO

thanks but doesn't really help.fitech do use B & C but I've read different things on what they are actually connected to so without knowing where they go it's a gamble trying to connect it to my alternator. I'd hate to connect it wrong on cook something.

I run a gm 1 wire on the dragboat motor, fitech ecu don't care. convert your current to 1 wire self exciting and be done with it

OK sir, I've also done some searching and also didn't come up with a solution for your problem.

What I learned is the GTO has a specific Mitsubishi alternator with a different plug than all other LS applications. You've learned this also.

There is no swap plug or way to make it work from a PCM setup for the other alternator styles.

Your options are trying to get a Camaro/Firebird CS144 alternator to fit OR like you said you can, trick the original to self excite.

I would recommend against a one wire alternator because they don't self excite and produce amps until the engine speed is high. At idle, it just spins.

Good luck!

The Fitech and OEM harness just sends switched 12v to the alt to excite it. A one wire self exciting removes the need for the wire. To run it on another type of alt you just need to figure out which wire on the alt needs the juice and it can be adapted.

IMPATIENT 1

That's just not true, most single wire alts are pulleyed for bbc or sbc balancers with smaller pulleys than the o.d. of a ls balancer pulley. Therefore a self exciting alt coupled to a ls balancer/pulley actually turns on way earlier than on a sbc or bbc mine turns on at 600rpms just fine, well below my 900rpm idle

Looking at which system to buy, kinda stuck on wanting the Holley Dominator so not to outgrow it. Was going to stay with ls oem for this car but a quality base tune from a pro tuner and a harness adds up to too much $$ for what it is but maybe. Reading this thread to eval the FITech, before spending my money, seems it is a bargain but a bit immature at this point from the reading i have done on these many pages and nothing wrong with that for a newish system as it seems to have good community support that is going well. Community support gets a lot of cars running on every system. I personally think I want a system ready for prime time and this seems to be the oem with pro help to get a base or the Holley. With that said, I am still keeping my options open to learn all I can through the next two weeks until LSFest weekend and then pull the trigger there or after I get home. If there was a lsfest sale on Holley I'd leap !! Have to say this FiTech is price appropriate for it's current place in the market. Still considering it. Holley may be under supported to an extent but if the hardware as well as software is much more mature and more solid it does not need as much support.

Hindsight 20/20 deal id went Holley hp at least, the fitech sux ***** in comparison 👎 I've fought it all summer long and still have the ******* fluctuations of the map sensor in boost which also shows up on the bouncing boost gauge(it's nice and new, not gauge!) I've talked to several guys with different setups that all are fighting the map fluctuations for no reasons👿 I have 1 more month of boating season and if I don't have it squared away by the end of that, it goes up for sale to fund the holley system. I've learned procal as much as I can , it's ****

I also have the gm map sensor and mine reads correct..I'm running 11.5 psi and it's consistent and steady.
