JWT ECU Question

I just had a quick question. My JWT ECU is tuned for 370cc injectors, stock compression, and turbo. My question is, what happens if I put the ECU without the turbo? Of course the 370cc injectors would be installed too but I mean how will the car/ecu react to it? Because if JWT tunes by the A/F or so, it shouldn't go into the turbo maps until it hits the right A/F which wouldn't happen without the turbo, so would the car run like stock? Lets say, if you blow the turbo, wouldn't/shouldn't react the ECU react as if it was normal (N/A)?

it will run just fine.
my sr runs beautifully when i disconnect the wga and run n/a.
like you asked, until the maf "sees" boost, the ecu wont add any more fuel than it has to.

That is exactly what I plan to do, install the injectors, MAF, FPR, and JWT ECU before anything else. The ECU will be working in N/A mode, so to speak, when there is no boost sensed by the MAF.

I was wondering about it cause I installed the FPR yesterday and was thinking since I have the fuel rail at acess maybe I should but I need new injector gaskets if I do so.. What sort of gaskets should I get for the injectors? I'm gonna be using the 370cc purple top ones, so would I get injector gaskets for those injectors or for the Altima stock ones? Part numbers/sites help too

So according to this site..

http://www.ultimatez.com/shop/?shop=...65660&cat=165&

The 300zx TT uses the 370cc injectors (purple top), so I would buy the injector o-ring set for this 300zx right? According to Kragen, the o-ring set should fit the 300zx injectors AND stock Altima injectors, part # 1580369

havent loaded that link of yours, but yes the gaskets follow the injectors, if the injectors fit the rail, it's implied that they gaskets will too.

Well went to Kragen and ordered the injector seal kit for the 300zx turbo so hopefully they'll fit, came out $30.00 for all 4
