Boosted Ecotec tuning time, need help PLEASE!!!

[Lefix]

Hey I just finished putting everything in and now its time to tune and i been reading but i dont know what to do with the VE and PE tables...

So far my tune is stock except i changed my fuel injector constant from 0.17800 to 0.10171 and changed it from really rough to really smooth..

I know i have to modify my VE and PE tables but i dont know how...

I have a Turbonetics T3 internally wastegated turbo with 42lb/hr injectors, HKS SSQV BOV, 2.5" IC piping, 2.5" downpipe and 3" straight pipe exhaust.
I dont have a FMU so i dont know if tuning is gonna be harder.. :P

Heres my .hpt file with the fuel injector constant changed only...
The name of the file saids copy of stock but i changed the constant on it..

Any help will be APPRECIATED!!!
Thank you thank you

I really need help..

Someone please help me...

do you have any logs? Are you getting knock?

[Garrett]

which map sensor are you using?

[Lefix]

Using stock 1 bar map sensor i believe...

[Garrett]

Using stock 1 bar map sensor i believe...

how much boost will you use?

1 bar is limited to 0 psi (absolute)

If using under 14.5 psi, use a 2 bar map sensor

over that, you have choice between T-map(2.5 bar) or 3 bar

my turbo is 7 PSI...

how is the MAP sensor effecting how much fuel to send out? Cant you just use the VE table and make it rich?

ajusting a car for boost is not just adding fuel, there is ignition timing to ajust


ignition timing is base on the map sensor readings

you need a 2 bar map sensor

Seriously?

There are people on the org that gotten ecotec's running with turbo with just the stock 1 bar map sensor... :P

Cant i adjust spark timing with HPT?

yes they did, but this is really hard on the engine, on the bearing, pistons, rings land, etc

with 6-7 psi you need to reduce the timing of about 5-8 degree

around 1 degree/ psi

the park timing is in the spark timing tables....

low octane, high octane...

The problem with the Ecotec is you can install a 2 bar map sensor, but the ECU will not use it. YOu can use it so you can pull in PSI readings while logging, but in a J-body we do not have a option to have the eCU read boost for the Ecotec and tune with HPT.

If I was tuning your car, I would leave the stock 1 bar map sensor in. The spark timing will need to be lowered at the 100 & 105 map columns of the the 4 spark timing tables to be a max of 14* to start. In boost, the 100 or 105 map columns will be used (depending if your in PE or not).

Do you have a wideband?

He could fake a 2 bar map sensor

all ecotec guys do that trick

Yes he can, but that does not change my statement.

[Garrett]

the PCM/ECU use the map sensor to know how much timing to apply

Russ Kemp

Yes i have a Innovate LC-1 Controller with a XD-16 gauge...

So under spark advance, there are 4 different tables, high octane, low octane, HO, LO

Which one of those i suppose to edit?

Do i NEED to fake a 2 bar?

What else should i edit?

I use 92 octane rating pump gas BTW... (the most expensive one...)

[Russ K]

No need to fake a 2 bar. Make the changes as shown. Do you have a proper cfg file to get the VE histograms to work?

Hey Russ, thank you so much for helping me

Right now this is how my spark advance look like... Current.jpg

And this is how my VE tables look like, my PE Delay is set at 2500, the numbers in idle VE is way higher than stock, my high RPM VE hasn't changed much, my low double and single fire RPM VE changed alot... should i change my PE delay to 0 like you told me to? Current VE.jpg

My turbo kicks in at about 2800-3000 RPM... i never push it to full boost yet, which is 7 PSI, but it reaches 5 PSI at around 4000 RPM...

Im going to change all my parameters to what you shown me, i just want to let you know that this is what i currently have...

I took out both of my stock 02 sensors, one in the stock exhaust manifold and one in the cat, do i need to put them back in? and since i havent put my stock 02 sensor back in the car, it is running at around 11 at idle, 11 during part throttle, and 12 during boost... i see 10's alot so i know im running super rich... im going to buy a bung and have m shop weld in my stock 02 sensor tomorrow, so maybe my car wont be as rich... i have a check engine light on due to the sensors, if i dont have to put them back in, how do i disable the light?

I also attached my hpt file after i changed my values to what you shown me

Thank you again for helping me, i cant imagine how shitty my car would run without your help...

[Garrett]

you had more timing advance with low octane than high octane

almost all the time, we use the same timing maps for both

Hmm, i dont really understand timing advance, but i use 92 octane and i thought i only need to edit the high octane table, my low octane is stock...

I should edit my Spark Advance table like what Russ shown me right?
