i know this is an old video but good stuff

Do you do the 411 wiring harness for people for $ I got 95 lt1 and I can't find no one the do the swap

[@manuelsarria1377]

Man that is cool what you doing. I have a 1994 Buick road master LT1 in my 56 Chevy truck would the 411 pcm work for my year? I only found information on 96 97 lt1?

[@TanTinPerformance]

It would work if you added a crank sensor off of a 96-97

[@nickd920]

@@TanTinPerformance It would have been really cool if you would have made a diagram of the ignition system on paper to share "after" it was done.

[@TanTinPerformance]

@@nickd920 there’s really nothing to the ignition system other then your coil and coil module. They wire up the same way as the Vortec do. All you add is a power to the coil and make sure your coil module wire going to the pcm.

How do you know if you got the right express van computer and engine there are 2 kinds for the same year

[@TanTinPerformance]

411 pcm, for a v8 with the 350 is the closest tune

[@albertvasquez20]

@@TanTinPerformance I have another question on horsepower tube connector paper on pin 21 it's say share with 411 c1-61 c2-3. What does he mean by this to solder the wires together

[@TanTinPerformance]

@@albertvasquez20 yes I believe I just soldered them together

[@blakerodriguez5999]

So I went carb… regret it.. have gen 1 internals in my gen 2 sbc…. Can I buy a crank trigger system for this conversion? I’m looking to convert back to FI… my opti hole is plugged since I have a balancer now..

[@TanTinPerformance]

Yea you should be able too

[@blakerodriguez5999]

@@TanTinPerformance dude thanks for the quick response. It’s been a minute since I’ve watched the videos. The 411 only needs the crank sensor right not cam?

[@TanTinPerformance]

@@blakerodriguez5999 correct it only needs the crank sensor.

[@blakerodriguez5999]

@@TanTinPerformance I don’t have to use the distributor right? I can do the coils over valve covers with the 411?

[@TanTinPerformance]

@@blakerodriguez5999 you can but you will probably want to get a cam sensor that bolts in place of the OPTi spark to get the full use out of the fuel injection

[@HWCapps]

Did you say the other person that wored 411 PCM - Hourse Power Tune ? Tube? ???? I did not fine him

[@TanTinPerformance]

Yea HorsePowerTube was the KZbinr that I got a lot of my info from

[@blakerodriguez5999]

So why wouldn't you need anything from the optical sensor? I ordered a cam and going with .026 head gaskets to raise compression hopefully to sound 11:1 after milling the heads. I’m just looking to be able to tune this thing Vs having to deal with a EPROM

[@blakerodriguez5999]

I have a 93 Vette btw

[@TanTinPerformance]

Blake Rodriguez the optical sensor doesn’t output useable data for the 411 pcm, depending on if your cars a auto you will also have to upgrade your electronics in your transmission for it to operate right. The way I’m running it is without a cam sensor and it running in batch fire mode instead of sequential fire injection

[@blakerodriguez5999]

TanTinPerformance I’ve got a 700r4 so it’s all mechanical.

[@blakerodriguez5999]

TanTinPerformance can you email a copy of all the wiring pin outs? [e-mail]

[@DukeSky]

@@blakerodriguez5999 Ola Blake, I have a 93 40th convertible. Doing a LTCC/Dynaspark conversion right now. 383, Procharger, long tube, Ram clutch. building it for Drag Week/Race week/ Street Car Take Over series. I do my own tuning via Moets gear.

[@user-bu3tg3ry3t]

Will a 0411 work out of s10 with v6

[@user-bu3tg3ry3t]

For 5.7 v8

[@TanTinPerformance]

If you have someone flash a v8 file to it

[@dunndoula7373]

How much would this job cost to do this conversion

[@TanTinPerformance]

I probably had $600 in parts to do the swap.

[@dunndoula7373]

@@TanTinPerformance man I wish you could do my 94 Impala I wouldn’t mind paying you

[@Q8RACE]

My car camaro lt1 1997 i have ls1 harness rework wairing ls1 harness to lt1 engine bt the connector c100 c230 220 i dont now how i swap to lt1 dash Harness

[@TanTinPerformance]

I don’t know how I would help you over the Internet, you would need both harness diagrams and just match the two up

[@Q8RACE]

Plz sir i won't esay rework wiring i rewok lt1 Harness to connector 411 like your work or ls1 COMPLETE harness rework to lt1 engine wish wise easy and simple

[@TanTinPerformance]

@@Q8RACE easiest would be repin the lt1 harness, if you want to run coil per plug you could use a ls1 harness but that would be more work and need for parts

[@carlgibson1196]

Can i have pin out diagram also
