Does anyone know what percentage increase in fuel is given by the computer at the point of vtec engagement? I have a ls/vtec that i'm trying to get the vtec set to engage at 5400, and it's bogging for about 200 rpm's. I think that I'm dumping too much gas at that point and flooding it. I have...

right, -35 is richer than -40

or, is that what your trying to say? after rereading your post, i think we may both be trying to say the same thing.

wrong. for example, -40% is leaner than -35%. think about it if an injector is running at -40% of what it can do, that is less than running at -35% of what it can do. think of 0 as stock. if you go poitive you will increase fuel, and the further you go into the negative the more fuel your...

your on the right track, it can't be told that there is no boost. but under normal driving conditions, it's not dumping mad amounts of gas either, unless you have it set that way. it's at it's leanest under 4k, the way most people set it up. so, that should be normal daily driving. the only...

it seems to me that it would be variable, only very few people take the time to try to set it up that way. it would require some time and serious data loging to see what boost you were pushing and where. surely if you knew that, then you would be able to adjust the fuel at those points...

i don't know if this will make sence, but i'll try. when using the hack the amount your setting it for is for the max psi your wanting to run, or in most cases the most you can run without running lean on fuel or throwing the cel. for the most part you let the ecu do the adjusting after that...

i bought my car and it already had an emanage installed on it. i wasn't the one who put it in and i certainly don't have a manual on it if there is one. doesn anyone know what the different dials on the unit adjust? i'd like to set the unit back to whatever stock is and work off that, but i...

thanks. rich would be less of a negative value, right? i also thought about uping the fuel pressure a little to make sure i stay rich. what would be a good pressure? and, someone on another board mentioned that if i'm idling fine after i set the injectors back, that's probably a good place...

i'm going to take my car out tomorrow to try and tune it the stupid way, on the drag strip. i'm acually ony going to try and get it running to about 6psi. i'm attempting to set up the equivelant of an vafc hack using an emanage and the profec e-01. i've got 370 injectors instead of the 450's...

thanks for all the help. i guess i'm going to suck it up and buy bigger injectors just to make sure. i definately don't want to take a big chance on going too lean until i can make my way to a dyno. does rc make saturated injectors in any size? i guess if i'm going to be spending money, i...

but, as far as a ratio, it would work to give an idea where the 370's should be at wouldn't it? even if it is a pecentage decrease of fuel volume, wouldn't you be able to find where the 370's and the 450's would be making the same fuel volume using that equation? if the numbers match, then the...

thanks for the help. i'm trying to make my way to a dyno as soon as possible. i'm just trying to get the car where it won't be throwing cel's every time it leaves the garage. learning one step at a time, thanks. let me see if i have this right, it's pretty much a math equation right...

i've got both, emanage with the profec. is it possible to do the hack with 370 iinjectors, or do you need at least 450's? and as far as acually setting up the hack, it's going in and getting at least -30% throughout the rpm range, correct? any idea what the adjustment would be like on 370's...

does any one know if it is possible to get the equivelant of the vafc hack out of a greddy e-manage? i have the profec e-01 that will allow me to change and edit way more shit than i know about, so i though it may be possible. and if so, how or does anyone know of a site i could go to to learn...

what method's are available through the emanage. the profec e-01 will allow me to edit and change settings in the emanage, to the best of my knowledge. what is the best method concidering my current set up?

the problem: my car is giving me a cel 3 whenever i get in high rpm's (between 5000 and 5500). so i lowered the boost to 6psi, still threw it. it goes away when i reset the ecu and doesn't come back on until i'm really getting on it. if it were a bad map sensor wouldn't the cel come on all...

isn't it possible that running rich can heat up exhaust? if you have unburnt gas left in the combustion chamber, wouldn't it then get ignited or partially ignited on the way out the exhaust. therefore uping the temp?

what is the size on the stock b16 injectors? if they're different, more specifically, the 16a1.

emanage and the profec e-01 to interface with it
