Hey, so it ususally takes about 5-6 tries to get the car started on e98. After that if I touch the throttle at all it goes super lean. Once it warms up car drives perfectly. Hopefully someone here...

Alright guys, the TB issue isn't related to the tune. Most likely a fault in the TB.

Everything was actually working really well for the most part except the timing. We turned off everything that...

For future reference, even if I block all the DTC's I still have to clear the DTC's to gain my throttle back. Very very weird. I have tried two totally different tunes including my old stock tune....

Can someone help me out here, having a strange problem. My throttle seems to work just fine on first start up after clearing DTC's. I can rev just fine, it doesn't throw the code. As soon as I turn...

Right now the only thing throwing me off so much is probably the map sensor. I can run the car and rev it just fine (stationary), I can pull the DTC's after reving it but the moment I shut down the...

The stock tune has all the same tables for the Ethanol sensor, I have heard they "don't work" though I haven't verified it.

I looked early. Biggest differences I'm seeing are my engine diags are modified to let the 3 bar run (this is new and not tested), injector size, my maf and VE aren't tuned either. We have the same...

Nice, thanks for sharing Kyle! I appreciate it! I think I'm getting really close on my tune. Had some more help last night on it. I'm actually able to get 55 gallons of e98 delivered to my door for...

This might read as kinda jumbled - sorry.

OK. So the stock tune has the tables to enable Ethanol but I hear they don't work. I swapped in what I was told, is a van segment and it started reading...

Thanks for the reply James. Think any of that would brick an ECU?

I've got in touch with one tuner that claims to have made it work right. The new PCM/ECU will be here Monday and I have a few...

Goal: Get a 2 or 3 bar OS into a 2005 CTS-V (LS6 motor) with a working flex fuel sensor.

Attempt: We tuned the car without boost, then flashed in a 2006 Silverado 6.0 Automatic tune into the car...

Doesn't seem like this should be that difficult?

Alright, so MAF is dialed in. VE is great for the cells I'm hitting. I could probably smooth it a bit more I guess but overal the car is running great!

The only thing I want to change now is to...

The guy that tuned my car kinda messed it up I think. The only thing in the tune I've changed has been a few rounds of MAF error percent, the injectors, and forcing it to open loop. Rather than...

Yes, the injectors are DeatschWerks DWK-18U0100788 which are "78" pound injectors. I used their tuning data. I'm planning on boosting it soon and didn't want to buy injectors twice. Do you think the...

Also, I noticed that my AFR goes pretty rich on WOT despite me having 14.68 across the board in the Stoich AFR table. Is there another spot in the tune that controls that?

Hey guys, can you take a look at my log file please?

I have the tune set to force open loop. When the motor is cold it wants to run way way lean, and once it warms up it runs rich. I'm not sure if...

I figured it out via a million youtube videos and a lot of reading. It does actually seem to use my wideband without me telling it to. Why and how I don't know. I figured out how to set it up for...

I don't have cats. Should I just leave it disabled?

I was able to figure out what DFCO was by searching but not COT. Are these things that really should be turned off? Sorry for the noob questions, just trying to learn.

How do I tell it to use my wideband then?

I went and opened Math Parameter. I'm using Predefined -> Lambda & AFR -> AFR Error.

Says 100 * ([50120] - [50121]) / [50121]

Where 50120 is...

So I followed this guide to setup my AFR Error with 3.X: https://www.youtube.com/watch?v=Jpqm2SEtagw

I'm a little confused about how the HP Tuners scanner knows to use my wideband rather than my...

I've been going after that Great Banish DVD which had MAF first. Is there one reason to do one before the other.

I just updated my sig with my go fast mods.

I have dual widebands in and am just now trying to tune my MAF with 3.0.

I have the MAF error setup and its logging correctly. I want to get a basic tune in now as I may not make it to a dyno for...
