Another fail for the early 03 5AT Sedans - Sprint Booster doesn't work
 

Since Technosquare stopped doing ECU flashes, I recently bought the new Sprint Booster to get some more throttle response. The Sprint Booster now have a 3 setting control setup: 'off', 'normal', and 'race'. They call these Sprint Boosters "Selectable". I ordered one on Tuesday and got it yesterday. I attempted to instill it and the Sprint plug that goes into the pedal assembly socket won't seat fully. It needs to go about 3 to 4 mm deeper. The issue is the pedal socket is shaped differently on the 03 early sedan. I opened up the 2003 G35 sedan FSM and sure enough, the Type 1 (early sedan 5AT) have a different pedal assembly. Go figure.

Sprint Booster wasn't aware of the problem, but now they are. They're actually being helpful. I researched the 02/03 Maxima since the early 2003 G35 sedans share some electrical arrangements, but the Sprint Booster part no. for the 02/03 Maxima auto is the same as the 02-06 G35 auto so it looks like a no go.

Sadly, I'm one step closer to getting rid of this car. Too much compromise for what I really want to do.

Good to know, Dave, thanks. I share your frustration with the early 03's limitations.

I'm surprised that there are THIS many differences between the two cars. Wonder why they changed it in the middle of the year?

I think Infiniti wanted to get the car out there asap. It is odd that they changed the ecu, trunk, etc. like 1/2 though the 1st year though.

Thanks for the info Dave. I too am considering my next car.

WHat are you guys considering?

I dunno. A G37 sedan, Pontaic G8 or GXP (gasp!). I don't think a CTS-V will come down enough in price when I replace this car. I like the M45 but it's hard to get one when the M37 has almost the same HP. M56 are way too expensive right now.

Those are all good choices. When you thinking about making the switch? Maybe I'll see you around the 2nd gen sedan area.

g37
 

had the same problem. just wrecked my ride last night here in NY.
had 03 g35 sedan rwd. I will be parting out my ride since I'm not covered by the insurance. Maybe I am a bad driver and stupid enough to drive out my RWD under the icy road condition. never had a problem with my g35. but could been better if it was an AWD IMO.
g37x is a way to go I think if you love infiniti and see lot of snow in your area. get a coupe! thats so damn sexy.
I'm getting one of those! :icon17:

^^^Yeah all wheel doesnt do anything in ice hope you can recoup most of the money that sucks

AWD doens't help when your trying to stop on ice, champ. :biggthumpup:

You had the same problem with the Sprint Booster not fitting?

Yeah, had excately the same problem. Plus I'm just wining about my wrecked 03 rwd.

Can't you buy the new pedal assembly?

When I was a dealer for them we were back and fourth about it forever.

Before I quit, we were going to attempt to use a Maxima sprintbooster. Seeing as how the ECUs were so similar maybe the pedal assembly also carried over. I never got around to it though...

Oh man that sucks. The maxima one man work.
