42# injectors and HPtuners?
Sunday, February 12, 2012 6:35 PM
Im getting a set of 42# injectors and hptuners. Will I be fine with them installed temporarily until I upgrade my fuel pump? Pushing only 7psi currently.

As long as you adjust the injector constant then you should be ok. At 7psi I think your fuel pump is fine.

It should be ok, just do a good tune.

To be specific, Fuel pump upgrade.

For 7psi, no. Doing the upgrade will bring down the injector duty cycle, making the system work better.

Good to hear I just want to at the very least convert to speed density and go from there. When I bought this turbo z it didnt even have a wiband

I just bought the car a laptop and hptuners and next. What is the easiest wideband to connect to hptuners?

I just picked up an AEM UEGO, it should be in the mail today or tomorrow when i get home!!!!
you end up figuring out where you're going to mount these gauges? I know you added that second one to your dash, which looks cool but you didnt like it or something, right?

I plan to mount the wideband in the dash bezel by fiberglassing it in near the speedo/RPM gauges...on the sides.

But if i dont do that I might just go the traditional route and just have them on the pillar gauge pod...like everyone else :/

Why would you ever run an LM2 in a permanent install? Its a hand held, the LC1 is a great wideband but the controller does not like heat. If you want to spend more the ntk is better, but for most people I dont really think its 60 bucks better.
