IE Integrated Engineering Tune Update

[Jhelmer]

I purchased the IE tune from ECS in Nov 2020. Car ran great. I later upgraded to dual pulley and purchased the tune for that. I did a track day at Road Atlanta in May and the car ran perfect. The next day (May 10) I received an email from IE about a needed update (Double Pulley Update). See below

"IE Tuning team here, we would like to inform you that a new version of double pulley software has been released for your engine box code, this version requires that you must flash back to stock and then tuned again in order for everything to operate correctly, this also includes if you plan on upgrading from Stage 1 or Stage 2 to Double Pulley. You MUST flash back to stock and then tuned again or the car will run poorly, after this is done you can change between octane/tunes like normal. If you are using fuel cut or fan control, you will have to reinstall that after flashing the tuned file. In this update we have fixed all errors related to a P1335 (Engine Torque Exceeded) codes, allowed the engine computer to understand the higher torque that double pulley setups make, enabled cold start as we had many complaints regarding emission testing issues. These changes have taken many months to develop, it has been tested with the most powerful cars out there and has been proven to resolve any and all concerns regarding DSG's dropping gears without any changes needed on the DSG side. One other huge benefit from this restructuring inside the engine computer has allowed us to provide more resolution to the accelerator pedal and the car overall should be easier to control, please allow a few days of driving to become accustomed to the new accelerator mapping."

I downloaded the update and installed it. The following week my car broke down, it turned out to be melted catalytic converters. My shop says it could have been the track day or the tune update. I guess its just a coincidence that I updated the tune and then cats failed. So i purchased test pipes and installed the cats on the mid-pipe to make them easier to change. The problem is the car has been running like crap ever since. I've tried every type of 02 extender and replaced the o2 sensors with bosch and it still has not helped. The only codes I get are in regard to 02 sensors. After speaking with two shops in my area they say I need a custom tune to eliminate the false o2 reading, which is going to cost me another $1500. So does that mean the $1847 plus $100 for dual pulley tune was wasted? I primarily use this car for track events. I contacted IE and they said they do not offer custom tunes. I have a bmw x5m as my daily driver, its got the Velos dp tune which I had to sign a waiver for. I am really surprised IE is getting such positive reviews. I guess if your only going to upgrade to a single pulley the tune is great; however, if you go dual pulley or crackle (which they offer) you will destroy your cats and there is nothing they are willing to do. I am heading over to Solo Motorsports tomorrow. $1950 for the IE tune down the drain.

What’s your cooling setup? I highly would suspect the track day is what cooked your cats. I’ve been DP for 17k miles on stock cats and still fine. Cat longevity is also dependent on how you drive your car. These engines produce a lot heat and the cat location is terrible, even so they can melt on the stock tune. I thought IE offered a test pipe file, you should inquire them on that. I’m sure that should solve the issues regarding the O2 readings.

I've got the APR supercharger intercooler upgrade. Yea I'm sure it was probably the track day. My issue is I moved the new cats to the mid-pipe. Its still throwing the o2 codes. When I asked IE if they had a test pipe file they said no.

Ok,

It would still be a similar situation unfortunately as the O2 sensors are either in different places or not being used at all.

This is going to affect the ECU of the car.

Like I mentioned you could check online/forums and see if anybody has found solutions for it.

I run ie dual pulley e40 file and no cats and car runs great. Idk what your issue would be but how do your logs look? Is it running too lean or rich?

[ANMS4]

I run IE STG2 DP +TB 93 for inspections, no cats with Vibrate J spacers and I do not any have a codes. Are you running spacers?

[Rodizzle]

I’m not going to bother on reading the comment . All I got to say Is “pay to play” .
Unfortunately your cats will go out tune or not that’s just the factors on poor engineering placements . You’ll see cats blow out or melt on stock cars , some last long then others but adding any modifications will push that to even a shorter life span .

You do not not need a “Custom tune” for your car to run right. I am on IE dual pulley E40, catless with no spacers or anything of the sort and I get no codes. I also track my car. My cats when removed were flawless. The tune did not destroy your cats. Like Rodizzle said, it’s a common fault with these cars stock, let alone tuned when temps are cranked from high performance use.

In for resolution. GL, OP. I hope you figure it out.

[Burkeomatic]

Is it possible he broke something else when his cat melted?

[Xmatic]

What codes exactly do u get?
It's a huge difference post or pre cat lambda

[Jhelmer]

Thanks for reply guys. This gives me hope and motivation. I removed the spacers on the test pipes when I installed the cats on the mid-pipes but I am going to reinstall the J spacers. I will get codes and run log today before I install the J-spacers. What insert do you guys have in the spacers, I have the medium ones in there now. My point with this post is the disappointment with IE and lack of support. I agree with you all regarding pay to play, I've put over $10,000 in this car in the past year. I plan on continuing to track my car which is why I moved the cats to a more accessible location, it also helped eliminate the crazy heat and exhaust vibration. For some reason though installing the cats further downstream has caused the car to run like crap which is why I reached out IE. It would be far easier for me to pay them to send me a file to eliminate the readings that are causing the issues. I live an hour-half from APR, I've had several of their tunes on my B5 S4 and VW's before that. Grant installed a tune at my house before he went out on own so I guess I am little spoiled from there customer service. I just thought I would try out IE with all the great reviews for the B8. Like I said, the tune was great when I was single pulley; however, since I went dual pulley the car has been terrible. I just installed test pipes and tune on my X5M, i signed a waiver for the tune and they had no issue eliminating emission codes. From what I am gathering from IE their tunes are not for cars with relocated cats and/or test pipes. Their tune destroys our cats and they say they don't. I just wish I would have known this when I went to DP and I would have went with another tuner.

You could flash back to stock and see if your car still runs bad, if that is the case then it is your setup at fault instead of the ECU software. I also have cats in the midpipes, without spacers, and the car ran fine on stock software (I did have fault codes + a CEL though).

BTW, I think any catalytic converter will also have trouble surviving in the midpipes with a dual pulley setup because of the heat (high EGT) and rich fueling; especially when combined with track driving. Have you measured your (calculated) EGT? Typical DP EGT on regular gas is around 1100 - 1200 degrees Celsius while reputable cat manufacturers state 925 - 950 degrees Celsius is the max temperature that their cat can handle (cheap cats will probably handle even less).

[Jhelmer]

That's exactly what the shop said yesterday. Every time we removed the codes they immediately popped back up. We removed the ecu and tcu tune and they are working on it again today. I forwarded your message. So if you move the cats to the mid-pipes you cant get rid of the codes? If they cant get it figured out today Im just gonna send it for the custom tune and eat the cost for the IE tune.

How is this possible. Does the E40 tune eliminate o2 sensor readings? Are you guys always running E40 or just when you hit the track?

If you relocated the cats downstream and your experiencing issues with drivability afterwards, I would check your car physically for a mechanical fault(or the exhaust that was just modified). The tune, whether it be stock, IE, 034, something custom, they will all run the same with zero issues related to the relocated cats.

I melted my cats on track, gutted them and installed 2x 200cell under the car. The only issue I had after was a MIL for P0420 and P0430. I had zero drivability issues and that would be expected on practically any OBD2 vehicle. I got a custom tune later to delete the MIL from activating from the 200cell and play with ignition to compensate for my local crap fuel.

Fyi, just deleting the MIL with a custom tune isn’t anywhere near 1500, especially if your willing to ship them your ecu to just tweak your existing file.

Thanks for the info. Car is still in the shop, they ordered two new bosch sensors and shipping is a week out.... Once they replace sensors with extensions I will reinstall tune and see if that is fixed. If not going to local shop for custom tune.
