I Promised Eagle goat some time back that I would get back to him and tell him how I went in regards to the injector data and information that he shared with me and my progress with the project.

I've been doing a bit of research! From what I have been reading the 4L80E went through big changes into the 1994 model year. (Mine is a 93),
The 1994 model year got:
New pressure control...

Transmission compatibility is a good call.
I had considered the transmission compatibility as an issue some time back but was unsure if I would be throwing good money in the wrong direction, I saw...

I have attached one of many tunes tried.In later versions of this tune I actually dropped the shift speeds and RPM to try to make it change up, without success. The gear/tyre is correct though there...

I googled it just after my last post and managed to get a link that worked. Apparently there is a region setting on the download that only allows US and Canada, according to a post on that forum. I...

No; I have heard of Blue Cat, browsing through some forums.
What does it do and where can I get it

The engine is a stock unopened 1998 LS1 with a factory OTR and SS bonnet with a tune, currently the O2 and fuel trims are turned off but the problem existed before that. It is making just over 400hp...

Recently did a 4L80e swap in my 98 Camaro. The car originally had a T56, I am running into tuning issues so it seems, I need some help with this as this has been puzzling me for some time.

I did...

I understand what say; I've noticed most tunes tend to leave out the scalar and as you say 78-92 isn't a massive increase whereas 78-102 is a huge air flow increase, I believe almost double.

I have had time to have a better look through your post and take much of it in, I found it very informative and actually learned a bit which is what it's all about. I am actually running the same...

I set the ETC scalar to 0.0210 from 0.0255

Thank you everyone for your response's. I understand that the throttle sensor also needs to be adjusted for the throttle blade in the new throttle body.

I understand updating the VE table through...

In a couple of weeks I hope to be getting my new LSX 454 running in my 98 Camaro with an 02 ECU. I may be a bit premature asking the question but I just want to get my head around it all: The start...

I promise I'll get back to you!
Though I could be a while getting back as the 98 Camaro the engine is destined for, is going through a lot of mods including the 02 ECU as I believe the 98 ECU would...

I have the data and I got two sets of the GM OEM # 12613412 injectors for each, the LSX454 engine and the 428LS3 and put LS3/LS7 injectors away where they belong. So! as it turns out we probably...

Thank you very much for your help everyone and for the link. Very much appreciated.

On calculating to .5 for brake specific fuel consumption comes up to 49lb. I found LS1 data in the forum for the for the GM# 12613412 injectors but not for the GM# 12609749 anywhere.

Thanks for...

Thank you for your reply AutoWiz and Eaglegoat and for the formula AutoWiz.

I do have LSA/LS9 injectors stashed away and actually had them in the intake manifold but I was concerned the conical...

Ok
I will be using the stock LS3/ LS7 Injectors for now to see how they go. If there are any issues I am intending to use Deatschwerks 42 lb @ 3 bar injectors as they would be good for about 48lb/h...

Hi everyone
I'm setting up a GM Performance 620hp LSX454 with a Fast LSXR 102, LS7 style intake. I am unsure if factory LS3/LS7 injectors are up to the task but they would probably be my first...
