Doing things right this time. Pics to come.

[hootyburra]

ready to start it tomorrow.
Pretty nervous.

I plan on leaving it on the jackstands.

Starting and idling around 1700 for the cams and lifters.

Running for 20-30 minutes to bring everything to temp then draining the oil and refilling.

Will it have an effect on anything if I leave the cold side piping disconnected? MAP sensor?

you can leave the cold side piping disconnected if you want. i've idled mine before w/ no intercooler piping while i was working on something

[gdoggmoney]

zddp for break in. Add a bottle of lucas tb zinc+. I run with a bottle of this stuf mixed in my oil.

Thank you. I knew it would be fine, just wanted some reassurance.

Already have the zinc additive in.

It's alive, idle is complete sh!t. I'm not even getting a reading on the AEM for a/f.
I tried logging block 32 in Maestro while I was holding the rpm around 2.
I was not seeing any reading.

I am using the 870 base file from Chris.

Cold side IC piping is disconnected.
Smells like sh!t, like burn your throat from the fumes.


Any suggestions?

not sure y ur not getting any readings. this is the guy who has never taken a log. i don't even have vagcom

[18T_BT]

Do you have your N80 resistored?

[hootyburra]

Do you have your N80 resistored?

Everything should be resistored off. I made sure to take care of that when I was cleaning up the wiring.

I am going to try and load a different file on an adjust for the injectors.

I am wondering if the 870 base file has VVT actice. I am assuming it does since it is for an AWP.
Also how do you rescale for an 80mm TB in maestro?

[Budsdubbin]

I had my N80/N249 unplugged running maestro emissions delete and didn't have a single problem

Just import the throttle vrs airflow and alpha n maps from the ID1000 80mm file to whatever base injector file your using.

Thank you.

Would you share how to disable VVT in the file?

[hootyburra]

copied the maps for the 80mm TB.

Editing the cam timing map based off a non VVT file.

Used to injector wizard to get a new constant accounting the 2008cc stroker motor.
It is somewhere in the area of .042 now.

It does not sputter on start up now. Idle is still bad. AF reading is still off the gauge. running way lean.


Open to suggestions.

[Budsdubbin]

You'd have to use a non VVT file and copy the fueling tables from the correct injector base file (main, injection correction, target filling, optimal torque should do it) aswell as BVC. Try adjusting your BVC by + or - .05 according to your A/F at idle (not your whole curve but just where ever your idle voltage is at) your lean so start by adding .05 at a time. If this doesn't help then you may need to go and adjust your alpha n map from 0-30%

I considering adding a MAF...

Add a MAF.

[hootyburra]

Add a MAF.

Would the TT225 MAF be pushed to it's limits?

I can use my bros for the time being.

I am looking at the s4 MAF, it seems to be one of the favorites.

[hootyburra]

Thank you Rac337 for the help so far.


I am not getting any readings in block 32 at idles.

I am going to start checking resistors.

I am also going to pick up a new 02 sensor.


When I start the car it idles great for about 5 seconds then goes crazy hunting for a few seconds until it completely leans out... past 17 on the AEM

No codes? Check the resistors for sure, n112, n249 etc all must have them. I Believe the VVT solenoid as well if not present.

No, once you overflow it you will go to EGO feedback anyways, and just target an AFR based on that I believe. It makes a world of differnece for spool and how fast power builds at various RPM

I am wondering if the VVT resistor blew out. The first file I flashed was for VVT.

I will double check the n112 and n249.

why not maf-less??

run the 3bar TDI Map sensor

[hootyburra]

why not maf-less??

run the 3bar TDI Map sensor

Want to run mafless.

Was going to use a MAf to get things running.

The 3 bar MAP, is there an option for this in Maestro or does is automatically adjust?

[gdoggmoney]

Can't. Theres a table size limit on the MAP sensor -- or at least not with "stock" ME7 memory locations. If theres a way around this, i'd love to know. I'm already over my MAP.


Also, i know you have not been around much but it's been all but determined that MAFless is garbage because your stuck with an 8x8 or so table, and these systems were truly designed to be MAF based because a MAF is the only way to accurately gauge lb's per minnute which is why every factory turbo car (including acura) has a MAF.

1979 Turbo trans am does not count

[schwartzmagic]

Go ahead and tune with the MAF. Just don't expect to make more than mid 400s. Show me one 1.8T car making over mid 400s with a MAF. Not saying you cannot get a more accurate tune using a MAF... Just cant make > 500 lol

The pro-maf's UM uses can meter ~800whp without an issue.

[18T_BT]

exactly, just because no-one has done it, doesn't mean it's not possible

thats not going to help people using VAG mafs and maestro/unitronic make more than 450.

Well...... Then time to up the game.

A Big Thanks to Rac_337 :Beer:.

The car is up and running.

It is violent. I need to stop melting waste-gate lines.

Heat barrier has been ordered.

Updates to come.

[groggory]

Can you post up some pics of your final surge installation?

[One-Eight GTI]

Nice Hooty, glad to hear... Did you get help from Rac337 with your tune or was the thanks for something else??

LOL i had to wrap my wastegate lines. i had a solid line for a while which was awesome too.

I will get a bunch of pics up of everything. The bay is still messy.

He gave me some big help with the tune. : beer:

I want to run hardlines... any idea what the precision wg thread size and pitch is?

With all the ot I am working new paint will be in store soon.
I also need a nee bumper. The intercooler won and the bumper got the cut off wheel.
Function over looks right... : banghead:

[Vegeta Gti]

so your trimming now in block 32?
