ACCEL DFI GEN 7 FOR THE LS1/LS6
Does the Gen7+ comes complete with a harness for race setup of LS1 and ECU and sensors is this correct?
The reason for asking is I am building a Vega for trac day use and some street (we have very few polution demands on old cars) with LS1 and T56 going in to it and I have all the hardware including sensors but I am missing the Harness and ECU.
Can I use Accel Gen7+
If so greate how can I get it to Norway?
I am a electronic and computer engineer so putting it in the car should be no problem.
I will be running no cats or other polution devices is that ok?
Can I throw away the MAF (more power) ?
Can I still connect the Autometer speedo up to the ECU and get a correct speedo.
I tried to find more info about it on the web page http://www.mrgasket.com but can`t find any LS1 details were do I look.
It is greate that Accel finaly gives us this

again thanks everyone at accel for allowing me to beta test this system I'll forward feedback tommorow evening ..
ps. Ken I need a multi stage harness might as well pump up the volume

The more I read the more exited I get

I mailed Accel about this a little over 6 months ago when I started collecting parts for my LS1/T56 project (In norway getting parts from US takes time).
I chose to buy a bare engine with sensors and injector but no alternator, a/c, PS pump etc since I am custom making most of it in to the car.
But I have been determind to use an afthermarked Engine Management system and now it`s here GREATE.
So now it`s just getting the engine/trans in the car and that should be a breeezzz compared to all the custome work put in to the car.
Thank you Accel.
Have a greate week end everyone.

surely has heir work laid out for them..At any rate the car here I been tappin on is 99% tuned ( I say 99% because I'm forever searching for that other 1%
) should be interesting to see the gains compared to stock pcm tuned with edit.I can already tell it will be pretty big change in torque and hp throughout the rpm band...
What is it, do you think, that is allowing you to produce more power with the accell than vs. a tuned stock pcm? Are you turning over 8k rpm and the stock pcm couldn't keep up? No doubt the flexibility is much superior, as well as the ability to change values in real time, and the ability to read boost (if you need to) - but in the end it still all boils down to factors that effect fuel and spark?
is it spark yes
is it fuel yes
is the ability to be able to control every aspect of both most definately..
does edit allow that ...maybe somewhat but the programmer is the sophmore and the factory ecm is the dean..
What happens often is the same situation that can happen with any efi - you set your base timing to xxx degrees, but then something else, say an IAT temperature modifier table, pulls out 2 degrees of timing. Upon logging you see xxx-2. Many people say "wtf, I set my timing to xxx, what's wrong with this".
To answer your questions - yes, you can remove the relearn process as it corresponds to a/f ratio. I do not believe you can directly alter injector phasing. Spark dwell is pretty much intelligently controlled in real time to give the longest spark possible while still allowing for proper coil recharge.
And again, don't get me wrong - I am not suggesting that the Gen7 doesn't have significant advantages over the stock pcm, I am just curious as to how those advantages tranlate directly into power gains.
If people are just throwing fuel in at random with a stock pcm then that is their choice - a good tuner with either tool is essential - probably even more so with the Gen7 since the baseline isn't (can't be) as optimized for this specific application. And drilling a hole in the TB blade says nothing about the tuning abilities of the ecm - the air you need at idle is a function of your displacement and rpm generally - since the flow through the iac is fixed if you exceed that you *have* to get more air in somehow.
Again, I don't disagree that the accell PCM has much more programmer friendly function, the relationships are clearly understood/defined, etc. - but just from my experience with aftermarket ecm's that doesn't translate directly to more hp/torque unless the base setup was unoptimized. This is with Gen6, Haltech, and FAST though (haven't seen Gen7 yet).
Now if you are doing something more exotic then I can defintiely see the benefit (FI, dry nitrous fueled through injector pw increases, etc.) and potential for significant gains, but on a heads cam or even built NA motor I would be very suprised if there was 30rwhp to gain for a given combination! I just don't think people should see this as a "power" mod, at least for the less hardcore combo's.
The choice is up to the owner in the end...
I am building a LS1/T56 Vega with Jaguar IRS and loads of custom pices to it built for hispeed road and track day use.
Also is the Gen7+ preprogramed for LS1 so it will start up?
Offcource it needs tuning but I was thinking of geting it started and driven to the tuning shop.

By the way Joe, where's my shipment!?! LOL...
