Probably the best way to do it is do a thin lip satoshi mod.

 

@Jstand how are you running 11's on stock injectors and no tune under boost? stock ecu should try and keep it at like 12:1 ish under max load right?

 

Maybe my gauges arent right I just took a picture full throttle coming home from work

 

Here's a better picture

 

At WOT he's running on open loop, so the ECU is not trying to control the AFR and is just dumping fuel based on MAF and who knows what other parameters. Also, he's in a 1st gen Tacoma which seem to handle adding boost a lot better than the 2nd gens from what I've read.

 

Here's my injectors 2 brown and 2 grey this got me nervous don't want a blown engine guess I'll put the 4.83 spring in

 

You guys are going to kill me for this but I don't have the wideband AFR yet could this narrowband be giving me false readings

 

That gauge mounted on your pillar sure looks like a wideband to me.

 

No it's narrow I hooked it up to the upstream o2 before the cat

 

Interesting. So you just tapped it into the factory sensor? Never seen that done before. What kind of gauge do you have it hooked in to?

 

X2 need pics and a possible write up (since 2nd genners have widebands upstream would like to see if it transposes)

 

Yes I spliced into the upstream O2 sensor blue wire it's a glow shift narrowband AFR I read up on this and most people said it wasn't accurate at least it's not as accurate as wideband narrowband gives you 10 different readings as opposed to wideband 50 different readings or something like that hopefully others will get in on this for better information

 

Cool yeah i just bought a wideband gauge (i mean to say that u only bought the gauge and not bunge or anything, not that i recently purchased it) and i was hoping to splice into the stock widebands succesfully

 

Narrowband sensors are 0-1 volt and Wideband sensors are 0-5 volt. Here's a good article on the two different sensors (http://www.innovatemotorsports.com/resources/news3.php).

The stock wideband signals on the 2nd gen are a current based, so you can't just tap into them like the narrowband. That's also why we have to use the AFR module with the mapecu3. If they were a voltage based sensor, you could tap into it, and the mapecu3 could send adjusted signals directly to the factory ecu.

 

Poop...

 

All this reading about wideband AFR us is a little bit depressing I think my next $200 spend is going to be injectors

 

@Jstand

Is it that the plugs are just different colors and not the injectors themselves?

If you didn't ever mess with the injectors, then why would they come from the factory mismatched in flow?

 

These are the original injectors I bought this new in 2000 not sure if they are mismatched but I'm just thinking now why mess with it if its working I just don't want to end up with a blown engine

 

So then the likely hood of the injectors being different is slim to none. Most likely the connectors are just different.

 

Does anyone know the flow rate of fuel injector p# MP4193 ?
