Our first LS2 E-Force kit installation is going on Bob's 2005 A4. First thing to do was get a base line for power. On the dyno the LS2 put down 344rwhp & 299rwtq.



Open the goodies.



Some light reading.

2005 Install?

I have a 2005 C6 LS2 and I ordered the eforce from Edelbrock in mid August. They have been in weekly contact with me as they are not able to ship the unit due to the 2005 operating system (the problem only exists with the 2005). Their techs have been having some difficulty getting the unit to work right and as of last Friday, they had 2 of the 5 systems working. I have been told by a company VP that they hopefully will have the product available within a few more weeks. Needless to say, this post confuses me and i will need to have a discussion with Edelbrock as to why I do not yet have a unit to have installed?

Thats such a great looking kit! Plus you dont have to buy a new hood:partyon:

I'm a little skeptical about the car only putting down 299rwtq for a base line..that seems really low.

Feel yourself lucky
You can save $1500 as GM now sells the ZR1 supercharger as a kit for $6000, Part number 19244103
It is better as it has the dual cooler bricks and far better warranty

Local here with a 2008 C6 with A6 transmission bought the EVS kit from a big mouth vendor gave little if no support.
The install document stinks but worse is the kit comes with a SCT canned tuner box.
Car was flashed and the transmission was totally F'd up.

The selling vendor, Eldelbrock and the tuner vendor all blamed each other and in the end the C6 owner had to take car to Chevy dealer who after reviewing the TCM for the A6 voided the cars warranty, charged the owner over $1,000 to fix. :WTF

In the short all the vendors screwed up and showed not one of them tested what they were selling as what caused the damage was the canned tuner box was force flashing the WRONG transmission software !
Worse it took all of them over 2 weeks to figure out the problem was flashing the wrong software in the TCM which says the tuner box does not even check first to assure the version and models match.
You also have no choice in maybe wanting just the PCM flashed and not the TCM and even though the tuner box was used to flash back to stock it did not fool GM as they could tell TCM had been flashed

After 3 months not one of the vendors has paid the costs for the damage and shows those vendors and 3rd party insurance you buy with the EVS kit is useless.
Also the engine tune was not very good and when properly tuned by our local tuner gains 40 HP more then the vendors claim who have been reporting low numbers for stock C6s and then claiming higher gains with the kit after install

There should be no reason not being able to tune a 2005 which means the tuner they use as shown above does not know how to tune and your better off not using the tunes that come with the EVS kit but the ZR1 kit is the way I would go

We tuned the car ourselves with HP Tuners. We did get a starter tune from Edelbrock, but it was in HP Tuners. My Edelbrock rep informed me prior to shipping about the 2005 program not being in the hand held flasher. That was OK with us...

Besides not bolting to the LS2 heads, The ZR1 kit sells for about $6700 but it’s not complete. The customer gets just a manifold assembly with injectors and rails.

The $6700 price ZR1 “Kit” does not include:
• The unique ZR1 front accessory drive
• No electronics, tune
• No heat exchanger
• No plumbing.

Will not fit under the stock hood. It requires a new hood. (ZR1 hood)

Steve -
What kind of power are you seeing these produce on LS3's? Have you done one on a 2011 Grand Sport with the MN6 that has the dry sump?

It looks like you are tuning them yourself, how would you compare the tune from Edelbrock to your custom final tune?

How would you compare the results to that of a Procharger on a comparably equipped engine?

eForce problems

By the sounds of one of the postings, I would guess that someone got a hold of one of the units without it being properly programmed. That would run into a series of problems. I have worked with Edelbrock on several occassions and they have always been right there to help when needed. That is why they have not yet shipped me the unit I have purchased. They want it to be right so I won't have any problems. I am still waiting. Hopefully, they will get the programming bugs worked out soon.

I emailed you to find out what you would charge me to do the same with the unit I bought from Edelbrock but I have yet to receive any reply.

The GM ZR1 kit does not fit the LS2 heads.

One of the guys priced out the complete kit from GM and it was ~12,000.

Most everyone that works on 2005 LS2 know it uses the E40 PCM which is different from the E38 and other PCMs used on newer cars. Anyone that has any experience with tuning knows you have to know what PCM the car has before flashing.

Shame the guy that represents a single tune will work on all LS2 PCMs.
