GIAC Large Injector Program

[wychoi36]

I'm hearing that the most recent GIAC large injector program is giving a pain to us. Does any know about this? I'm trying to choose between GIAC and APR.

[Carlitos]

with correct injectors there should be no problem.

[scorneil]

i have GIAC BI and have no idea what you're talking about. have had it for 4-5 months now.

This is what I am talking about.

giac puts a firewall on their newest software that makes it impossible to tweak the file via lemmiwinks. Not only does this limit your ability to alter your file for personal preferences, but it also prevents an east fix to the aggressive timing on the giac big inj file. This means that once you go giac and you experience engine pinging (a common problem, I would post a link but my phone does not copy/paste), you are essentially stuck with it unless you swap plugs or something to compensate for the mild detonation. In my case, plugs didn't work and I am currently running a file that is conservative.... and I just consider myself lucky to have a good tuner that cared enough to help me out and stop the pinging
sorry for the ramble

with correct injectors there should be no problem.

Will TT225 work without any problem?

[AudiA4_20T]

there were a few threads on this, there was a plug that was found to fix everything... and I can run lemmiwinks with my BI file

[scorneil]

didn't know anything about that. i am running TT225 and haven't experienced any pinging.

would be good to know what plug we're talking about, i would probably throw that in to be safe

Please let me know if you find something. I do not have much luck with the SEARCH.
by the way, I go to Toronto frequently since my parents are there :)

cool man, tons of peeps around here and AW from Toronto

The new file is paired with a boost controller function in the file.
You can use this to set the boost to a safe level for your car and
hardware. The upgrade is 100 dollars since it is only paired with the
boost controller function. I should note that you will need a vagcom
cable to adjust the boost.

At this point, I'm not trying to do much stuff, such as controlling the boost level. All I want to do is having a large injector program and have fun. No more headaches.

Here is my question. If I go to GIAC dealer and have large injector file + TT225 and 710N DV Valve changed, will there be other items that I have to correct in the near future? It seems like I can walk away with that setup with APR Stage 1+. I just do not want to have a headache after doing a chip upgrade at this point.

All I want is have the large injector file and walk away with smile :)

[Tgr_Clw]

A truly bulletproof stage 1+ setup will need the following:

- exhaust
- test pipe or high flow cat
- upgraded DV
- upgraded intercooler
- upgraded clutch
- upgraded turbo inlet pipe and throttle body hose
- upgraded clamps all around

After that you'll have 0 problems.

just tell me to buy S4 or something lol
i'm not looking to spend that much money.

Have to pay to play.

I have been running the GIAC fx file for years now with great results. The best results came after a plug swap to a Porsche plug and a reflash to a more recent revision of the software a while back.

I am selling off the injectors now and moving on but I am staying GIAC, never regretted the decision once.

I'm sorry, I don't quite get it. When you say "plug," do you mean the spark plug?

[QuattroRocket]

Yes I replaced the plugs a few times till I got a setup that has worked 100%. Do a search for posts from me and you will find it.

If you need injectors lemme know :-)

Thank you for the information. I do have TT225 injectors in front me. :)

thankx

After having GIAC FX for a year, and getting no resolution to my pinging (no help from GIAC either), I finally bit the bullet and switched to APR 1+.

I couldn't be happier. Pinging is gone. Plus, APR gave me the fully loaded (all the programs) software for $500. APR isn't as aggressive up front, which is where i was having the pinging issue. But it makes up for it later on.

Also, APR 1+ doesn't screw up your MPG display, like GIAC FX does.

I would 100% recommend APR over GIAC, even if you have to drive to a farther dealer to get it.

Here is my current situation.

GIAC: abour 1hr drive. $720.00 Cash for Flash + Injector install + DV install
(I bring my injectors and DV valve)

APR: 3hr drive. $600 + Tax. Flash + Injector install + DV Install
(Same. I bring the parts.)

money wise, I APR gave me a better option as well
so now, i'm debating lol

[pondside36]

Just throwing this in there... the DV install is super staight forward, it only took about 30min if you are looking to save money on install fees...

[Rich4114]

I think I may have this same issue with the pinging. I have the GIAC 1+ file with BKR7E-IX plugs and have strange issues if it's too cold or too warm outside. If I'm idling for example, my idle will sit steady at 800 RPM's but then drop down to 600 and spike up to 1200 and settle back down. Is this considered pinging? AWE told me I'm supposed to run the stock B6 plugs in my car with that file but it seems like so many people have to run something else.

[gtimart]

Rich, GIAC themselves told me to run stock plugs with stock gapping. I had misfires at high load so I tried BKR7E-IX @0.028" and they were too cold for my climate. One morning the car wouldn't even start anymore, the plugs were full of carbon. Tried BKR6Es @ 0.028" and I had less power and it was still shaky under load. Now run new stock plugs @0.030" and all seems well.
That being said, there are people who successfully run other plugs. I guess it depends on how you drive, and what climate you live in...

[rccks96]

I run BKR6E's in winter, and BKR7E's in summer.

APR 1+

Did you try this in winter or summer? I dont think PQ and ON climate is that far off and was considering going to a colder plug

[chris@penskeaudi]

I say with the right fuel injectors you should be fine.. GIAC would no release a rogram that would have issues

[cuco33]

I'm going stage 1+/2 soon. Def this year and I was leaning GIAC. I need to get injectors cuz everytime for local dub shows the vendors can't get the injectors in time... then again I usually ask a few days before the show

[pondside36]

I just made my appointment to GIAC FX for Monday and I'll give you a review after I drive around for a bit since it will be the newest version...

Are you running the stock plugs? Also, GIAC recommended the seimen 380cc injectors. do you think the tt225 injectors work better? thx.

[manguyen]

why is APR 1+ 600 bucks???? i got my flash for 500 for 2 programs.

[BangHatch]

Also, APR 1+ doesn't screw up your MPG display, like GIAC FX does.

Could someone/anyone explain that? With the GIAC the display is "inaccurate" but with APR it is? How so?

[A4Avant02]

Take a look at this thread for some info on adjustments to the mpg display.....

[gtimart]

audipotential, I think there is a climate difference, unless you live in northern Ontario
Anyway, I guess a lot has to do with your driving style. I have a wife and two children so 95% of my driving is relatively conservative. It's that 5% I'm alone where I mash it at times. It's probably not enough for colder plugs, and I was running them in winter too (silly me).
Now that I'm back to stock plugs, I'll have to wait for hot summer days to see if I still have misfires. In the current setup, I feel the engine is a bit rough when under full load on the highway, but I have no misfire codes so it's probably normal.
I have the Siemens 380cc injectors by the way.

Also, I highly doubt that any program using bigger injectors would "not screw up the MPG display" as this is computed using injector opening. Bigger injectors = more fuel belched during the same period. The MPG computation doesn't know about it.
Follow the indicated link. I did it and it is closer to reality, although not quite there.

[Rich4114]

I'm running the Genesis 380cc injectors with BKR7E-IX plugs and under accelleration I'll notice a slight rumbling when I hit like 2800-3600RPM's. Also I seem to have more power/torque if I don't got WOT until I get the RPM's to like 2600 (is this because I need to wait for boost to build up or something).

I'm going to try and just put the stock plugs in at the factory gap and see if there's a change. There's always that fear in the back of my mind though that there's a slight boost/vac leak or my N75 valve shit the bed though.

I've got APR 1+ spot on with my MPG display. They must have put something into the ECU software to correct it.

With GIAC FX, i was on the max setting (115) and i was still off by about 3mpg. For example, if my display said i was getting 25 mpg, i was actually getting 22 mpg.

After having APR 1+ for a few weeks, I had to back the setting down to 105, and now it is spot on.

Don't ask me how APR did it, but they did.

[diztek]

i think im gonna try the stock plugs again. does anyone know what the part number is for the stock plugs? lol, its been so long since my car ran stock plugs.

[wychoi36]

$600 is flash + installing injectors and DV Valve. Not sure whether I can get 2 programs for 500. I guess I can ask for it, since even ECS tuning is selling 2 programs at 500 bucks. Thankx for the information.

by the way, do I need a special program or part to switch programs back and forth using cruise controller if I have more than 2 programs?

Thank you,

Thanks! So with GIAC it is fixable...

But the with the APR program, there's no need to adjust anything? It "knows" youre running a bigger injector?

[Papachristou]

1+ really needs some supporting mods like intercooler, exhaust, TIP and at some point clutch... i did logs right after i got it and my IATs easily pushed into the 160 degress range, now with my intercooler they stay 10 degrees above ambient....
I love my APR program and it was $500... i got my injectors from manguyen in two days at a lot less than what APR/GIAC was wanting for them!

[oregonaudi]

I run the mods in my sig and had significant pinging with every plug known to man... even QuattroRocket's Porsche plugs.
I definitely feel that GIAC is more aggressive than APR (could just be "spikier"), but I have articulated my fair share of pinging warnings. BUT, I live in the PNW, and we are known to have shitty gas... so I'm sure that had a little something to do with it.
