About 10 hours over two days for myself and it was nothing I've ever done before! Would have been a bit faster but didn't realize I had the spacers for the injectors till the next day!
Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?
ok cause i am looking to hit around 200-225 hp...all i want really cause this car is daily driven so if i supercharge the ecotec and run full exhaust and a decent intake can i hit this mark easily?...also what else is required after i get this on...the gm reflash? and will it need to be tuned by a shop with a dyno or is the reflash basically that?

you will def hit well over that. One of the memebers from the cav crew I am part of got dynoed at 215 whp I believe. Completely stock besides a short shifter and an intake. In order to run without problems you either need to pay gm for the reflash and if you are nice with tuning purchase hptuners and tune yourself. It's best to rather have someone tune it with hptuners over the reflash because then you can explore past not only your stock rev limiter also your stock fuel cut for once you are actual able to trap over 108 mph...

i helped Marchi1 with his...it took 3 hours.....and i dont have any skill
you CANNOT use hpt on the EcoTec GM Reflash
you can however tune the LD9 s/c reflash A.K.A 2.4 with hpt
You take a women and X her by PSI devide the legs and you can then juice the car......LOL
so can i tune it without the gm reflash and just use hptuners?...what exactly does the gm reflash do?...just the rev limiter?

it calibrates the computer to be able to accept the changes needed with the addition of the s/c, just gm's will be more conservative to keep everything safer

maybe a little longer, and there were both of us working on it.
Of course removal time was much less.....

but if i understand right if i get the gm reflash i can't use hptuners on the computer after that?...is it possible to install the s/c then just tune it with hptuners and be done with it?

Correct you can't use HP Tuners after the computer has been reflashed with the GM program. If you have HPT and use that opposed to the reflash then that would be fine, it's what I currently have.

what is more reccomended...a tune with hptuners or the gm reflash...what does the gm reflash do...just mess with a/f ratio since theres alot more air being slammed into the motor and does it affect rev limiter and speed governor...also got another question. my g/f's dad said something about an electromagnetic clutch on the s/c so when i don't want boost the pulley just spins free...i don't think the gm charger has this feature and i don't really see the point...cause if i tune for more fuel etc if i am able to "shut off" the s/c won't that mean the car is gonna get too much fuel when its not boosting?....anyway don't flame me cause its not my question lol thanks for the help so far

Mike have you searched on this topic?
The is no clutch to activate the Eaton M62 genV in this application,. If you aren't in boost there is a bypass valve so the engine runs more efficiently.
Whether you do the reflash or the HP tuners is based on a couple of things: 1) how far you are planning to go in adding power to your car, and more importnatly 2) what your, or people nearby by you, ability to tune a car using HP tuners. You can do much bad if you have no idea what is going on.
The GM reflash modifies alot of the stock programming with a new prgram because you have changed the volume of air going into the engine, and the kit also include a different IAT and pressure sensor then the OEM application since you will have the ability to be over 1 atm, in lieu of at 1 atm, or pressure. Also the kit using a different injector, with a corresponding change in the innjector constant, so that you are spraying the right amount of fuel as well.
and FYI you can't mess with the A/F as that is non changeable that is a result of the engine running, you actually change other parameters that result in a change in the A/F.
best suggestion, get a spare ECU, have that reflashed with the GM SC reflash, when you feel more confident, or fell like you can do it, or find the people who can. Put your oem ECU back in and tune it with HP tuners.
Did that help?
ok i have searched on this topic on many websites...just double checking things to make sure i got any questions that i can't find answers to...so sue me if i ask a couple of questions that have been asked before...if you don't like it don't answer me...and for your information your last post did help alot so i do thank you for that. i think i will more then likely just get the gm reflash done cause i don't plan on going much more hp then what this will give me...just the s/c, decent intake and complete exhaust then be done with it. so i think the gm reflash will do me just fine

it took me and my buddy a weekend to do cause were slackers LOL
If i were you i would get HPtuners if you have the money i have the GM reflash and im trying to save up for HPtuners. the GM reflash runs fine but i really would like it to be better.
my g/f asked me about the clutch on the s/c becqause he said when its not boosting and the pulley was able to spin free then it wouldn't be as hard on the bearings on the inside of the charger. so what is the life expectency(sp?) of the s/c anyway?

im confused....
you scratch my ride IMA EAT YO CHILDREN
g/f's dad said that actually and if that confises you then i don't know what else top say

Yeah i have a friend that worked for eaton he said that when the SC is not in boost that the pulley actully spins free without the charger being used.
I dont think so......
It uses a bypass valve to redirect the air around the rotors when not at wot.

anyway you can send me your HPT file man?! I realy need a good tune to start off with bro!
Some superchargers use said clutch to de-activate when not in boost. Mercedes had this, and I think the s/c sitting on the Northstar for the V-series XLR and STS might use them as well, but I'm not sure.

Yeah but being that this was a post about the m62 for the ecotec i figured it was safe to say that
