RE: w/m install in progress. questions...
ORIGINAL: neur0tic
Nate, with the gt3076 turbo package from Pagparts... what size injectors would they give me for that and what type of tuning? Do they just send another ECU altogether? Is it standalone? and will they ask what Im looking for out of it or will it be a prefab product? Reason being... I'd like some type of w/m sensing software embedded in it.
I do believe he uses 630cc injectors and is a Chris Tapp or simular tune. You should have to send hime your ecu and he will flash it. Its just like stock to where it will adjust timing based on iat and knock.
You can get a low level indicator LED upgrade (uses a bobbing device to read fluid level and sends low voltage signal to an LED when low or out. I'd like someway to integrate that into the ECU to retard timing once I run dry on w/m. How possible you think this is? Would it be as easy as them embedding it and installing a wire terminal on the ECU for the low level indicator signal wire to attach to?
Like said above, if you happen to run out, the timing will be pulled to a safe level. It would be like it would be stock if you got bad gas. I plan on just using my ww res so i have the indicator and if i use ww fluid, i can use that still also. I was thinking about getting a separate bottle installed and then run it into the ww res if i want to hold more fluid.
Ok... now im going to sleep. I don't know why I think you'll know the answer to any of that... but for some reason I bet you do. lol

RE: w/m install in progress. questions...
But if the ECU advanced timing and then began to retard timing once fluid got low... then why am I having to advance the timing with lemmingwinks? Thats what I mean. I want the ECU to be already set at the timing I find best with the water/meth injection. that way I don't have to go in with lemmingwinks and tweak it with the new sw. I dont get how the ECU advances and retards it if I have to do that manually tomorrow. Or does the stock ECU (even with aftermarket flash) limit the advance of timing, causing me to have to manually advance it with uni or lemming. ?

RE: w/m install in progress. questions...
the tunes have a timing curve wriiten into the ecu to a certain max and if the knock sensor and/or iat sensor see certain things, they reduce timing (no contol over boost).
Example
the red line is the timing in relation to rpms. Its high prespool to get the turbo spooled and then dips as if peaks and then picks back up when the turbo starts to level off/fall off, whatever the case may be. It will never increase timing above these limits on its own, just lower them if needed (high intake temps and lower octane gas). This is why you will need to raise it will lemmi, it can easily handle the max and now is able to handle more. The reason you noticed a gain already is your intercooler didnt lower the iats as low as possible and possible the gas isnt high enough octane so a deg or so of timing was removed. This will be the same with stock or BT sw. You have the power to increase it manually if you like, but the sw is wriiten for 93oct and no w/m. You could run a file for 100octane, but that would be worse if you ran out of w/m than just turning up the timing with lemmi.
Hope this helps
