Another S/C'd member worried about his AFR

[cali yaris]

The blitz fuel controller does that and only that -- it does not adjust timing.

Is not like that... the problem is not running lean.

As largeorangefont explained, there are 2 things that could kill your engine...
Temperature and Knock...

Running lean will USUALLy lead to higher EGT (exhaust gas temp)...

This can be sorted by either adding more fuel to the mixure (making it richer) or by taking away ignition timing.

That's why it was said that even with those AFR readings... if the ECU or the black box were taking timing away... then you were probably OK


Talking about EGT... why you guys haven't picked a pyrometer? Those are not that expensive and would definetely help you sleep better at night...

Has anyone tried to disconnect the black box and see what happens? Ideally would hve to be some one with a wideband installed.
That would answer the question if the black box is actually doing anything at all...

I don't really think that is the problem...

When we have forced induction usually the largest the exhaust the better (within a range of course)

You need to remeber that no car is the same as no Dyno is the same...

Weather condition and other factors could have affected your final output.


Anyways.... isn't 20whp withing the range of the tipical gains offered by the blitz unit?
I mean... in you car that is a 23% increase in HP...

The tq still looks a little weak... but still within range...


I can see these kits putting 10-15whp more with a tune... if there would only be an easy way to tune it...

it..

Yah true. When I did the dyno run, it had to have been atleast 85 degrees (HOT!). I don't think my 2.25" headerback exhaust would have me lose HP, definately torque, but NOT as bad as it is showing.

Noogie! Do it!

Haha, it wouldn't be that easy or cheap to go back to my stock exhaust setup. But I know what you're implying.

We aren't capable of doing that unless we have a standalone ecu, correct?

i undid my pvc valve to make hooking up my boost gauge easier and there is a ridiculous amount of oil coming out of my engine and into the manifold. something has to be very wrong

[PETERPOOP]

lol. well make a new thread. :P

[whooppee777]

i figured everyone was already looking in this thread

[PETERPOOP]

true. good luck

thus i installed an oil catch can

[Nexus1155]

Why is everyone having problems with this kit now :( :( :(

[PETERPOOP]

Because nothing can be easy! Especially FI! doh

[whooppee777]

its aftermarket shit, its never easy. but thats y we do it

i know its normal to have a little bit of oil coming through, but i have a shit ton WAY more than normal

[whooppee777]

and by the way my afr go to the 12 range at WOT but tend to stay in the 14 at 1 to 5 pounds of boost

Well you're definately not running as lean as noogie and I. I ordered a scangauge II from garm tonight. Hopefully I'll get it soon and have more accurate readings.

I am curious of your A/F readings since you are using the 1.8 tb.

[whooppee777]

urrently planning a group dyno day with some other tuners in the area within the next month u'll get ur readings as well as graphs

[Nexus1155]

it seems like proper tuning would net this supercharger alot more power. people who arent running as lean as other nets 10 more hp?! imagine if you were actually running well...
