running out of fuel

[Sho Amo]

Im planning on stepping up to a 125 shot soon. what i wanted to know is if there is a way to tell through the tweecer if i need to upgrade the fuel pump and fpr. right now i have a 155, with a stock fpr on a 100 shot. i just bought a set of 30# injectors for 80 bucks and ill probably be throwing those in soon. i know that i shouldnt be going over 80% dc for the injectors and thats why im upgrading.

i havent had a chance to datalog with the 100 shot yet because i cant get any computer to connect. The only computer that actually works correctly is my desktop.i cant get my sisters vista laptop to work and even my friends xp.

I can tell you that you outta have a wideband for that. My 150 wet shot is pretty ugly with full timing, lean as all ****. Thats with another fuel system feeding the nitrous. 125hp on a dry may be too much, but the only REAL way to tell is with a wideband and some datalogging.

You wussy! I have been running stock 3.2 injectors with the 100 dry shot for a long time now. You can run up to 90% duty cycle with no problems. I am still on the rich side when spraying.

Welcome to the wonderful world of the TwEECer.:splat:

True, true. IT's a shame the Drags were canceled at the convention. I was looking forward to giving you a good spanking!:asskick:
I guess we had to drink and watch fireworks instead.

You mean to tell me the melted spark plug you showed me was a bad thing?

 

[St Louis SHO]

It was the serious pinging that had me worried... :swing:

 

[Sho Amo]

any recommendations on wideband setups?

btw i was running and i think brian is running stock timing with the 100. i think i should be fine taking out 5*. especially since im only going to go up to 125 and not 150.

hey brian check your pm's im ready to put the heads together.

PLX seems to be a good one.

PLX seems to be a good one.

Yup, thats what I run as well as brian.

 

[St Louis SHO]

I'm running an FJO, it's ok, and it works with my nitrous maximizer, but PLX should piggyback with the twEECer IIRC.

 

[SHO_DOODmorrris]

most good widebands will have a pcm output on them. im running an AEM wideband cause it was cheap and i was on a serious budget. seems to do the trick for me!

You can watch the injector duty cycle and pulsewidth through the Tweecer, and see if your injectors aren't up to the task. You'll need a laptop to datalog with though.

SHOGUY89 = Old Nitrous ******. Used to have a $400 a month nitrous habit.

If you've got a wet kit and install 30lb injectors, you won't have to do anything to the nitrous. Just calibrate the tune to make the injectors work in the engine and the nitrous system will do the rest.

I use the Innovate wide band sensor and setups.

I thought this was a bad idea on the SHO, unless you're going direct injection (which I don't think he has).

True, but mine hasn't worked for several months now. A new sensor didn't fix it, so it's time to rip it out and get another one.

Yeah, you're right. I meant to say Dry Kit.

 

[SHO Dude]

With a Dry Kit, the nitrous system nails the fuel pressure regulator with a calibrated pressure to jack up the fuel pressure and add more fuel thru the injectors. If you increase the injector size, the same nitrous pressure will deliver more fuel and maintain the AFR and correct for the bigger nitrous shot.

I will be back in town next week. I'm doing the family vacation in the outer banks, NC.

P.S. I could pick them up on my way back. I'm guessing I will drive by close to your house.:wave:
