fuel lag

[06rolladude]

Fuel lag... WTF is a fuel lag, fuel doenst lag, you have constant pressure in the fuel system and the injectors are opened with the ECU. You wont help anythign by getting some random CC/min injectors and leaving the software in the ECU stock.

How do you know you're running lean, as far as I know the stock ECU doesnt have datalogging. Plus at certain rpm/throttle levels, its ok to run lean, thats how you get mileage and emissions friendliness.

Really, you gotta read up on fuel delivery now, before you boost, if your knowledge is this kind, you're gonna have fueling problems with the boosting. Unless you get a ready made plug and play kit.

im getting the kit from hass/turbo-kits.com so it comes with emanage and injectors i also already have a walbro in tank pump cant remember the exact lph but i was explained by a toyota tech that the injectors are already at 90% so when you add more air they are maxed out very quickly i duno anything about the stock injectors but i was just curious...thanks for your re:

[06rolladude]

and it was explained to me as fuel lag because the engine lags due to lack of fuel

your engine wouldnt lag due to lack of fuel, it would detonate due to it.

Time to change your tech.

[06rolladude]

so tune + emanage = good idea ? lol

I dont like piggyback computers, they alter the signals to the stock ecu... you're still using stock ecu maps, which is a restriction. I'd rather go for fully programmable ECU, such as KMS, Tatech, Haltech, or even megasquirt.

theres no way your making so much power off of a mildly modded corolla to use up all of the fuel your getting. YOUR TECH SMOKES WAY TO MUCH WEED!

Considering most injectors wont function properly if they're at the 90% range. They start to be open constantly.
