Hi to all interested in this topic...not positive if this falls under the DIY PROM thread, but posting here because it relates to the EBL.

Im concerned with wiring my EBL flash to a 0411 PCM to run the Transmission in my 1999 Tahoe with a currently collapsing VORTEC motor. I would like to keep the VORTEC block because of its 1 piece rear seal, and durability this motor has shown, along with its power potential of the heads.

I LOVE my Vortec motor as it is, but im one to say, "If its stock, It still sucks" ha.... My ultimate goal (over the next couple years) is to build a complete Forged Vortec Roller Block, with Twin Turbos and a TPI setup on top ran by the EBL.

This all seemed good until i finally realised that my transmission has to be connected to my EBL via the VSS and other sensors to run the trans.

The EBL, Wiring and motor are currently on a home built test bench, and are not a huge concern at the moment, but would like all the info i can get now to build this right the first time.

PLEASE...Can anyone help me with the wiring diagram to adapt the EBL to my 0411 PCM. Ive searched google for anything related to this topic and just cant find ANY real help with this issue.

I really appreciate anything you guys have info on or can turn me towards, it would mean a lot to me. Thanks all for viewing and info.

 

Basically the engine control stuff gets moved to the EBL ECM. Items such as IAC, injectors, CTS, TPS, and so on.

Some sensors get shared, such as the MAP, and maybe the TPS.

Run IGN+, battery power and grounds to the EBL ECM. Grounds must go to the engine block.

For the VSS to the EBL, it appears that the VCM output that feeds the cruise & radio will be a 2K PPM. Even if it is 4K PPM can change it in the EBL Flash ECM's calibration.

Wiring for the EBL ECM is on our web site:

Since the EBL ECM won't be controlling the TCC be sure to zero out the TCC lockup spark retard table.

Twin Turbos and a TPI? I Don't think that is a good mix no matter what controller you use. Or am I missing something?

 

??? Not sure about that, I see a lot of people running turbos on the TPI's, Ive even seen forums on other sites that people are tuning the 90s Typhoon And Syclone ECMs to run on the V8s, its just not the route i want to go.

Ive been running the EBL Flash on my 89 377 Stroker TBI motor for the last year, AND I LOVE IT, by far the best aftermarket controller for GM Application to date. Plus the EBL has N20 controllers, and yes it supports up to a 3bar map sensor for turbo/ Supercharged apps.


And Thank you Rbob, for the reply, makes more sense now after yo
u explained it, and thanks for the reminder about the Grounds going to the block, almost overlooked that for a min...ha. Thanks again

 

Checked a re-pin guide we have here for a different ECM and these are shared:

Battery+
IGN+
Grounds (system & sensor)
TPS
Distributor reference +
Distributor reference -

If a knock detection system is desired an external knock filter needs to be added.

The PCM will turn on the SES/CEL as it is now missing sensors. So can move the SES/CEL light over to the EBL ECM.

To go along with the ECM grounds going to the engine block, the ECM case needs to be electrically isolated from the chassis.

the wiring for the injectors and the sensors are going to be made from an old camaro TBI harness that has a knock sensor already, and will be running the EBL FLASH for a TBI but with the port mod (havent sent it in for port mod yet) to the TPI injectors.

Do I still need an external knock filter? Or does the EBL or stock ECM, 1227747 have one?

 

External is to the ECM, so need one. That harness should have a connector for it. Flat 5-pin connector with 4 wires.

The knock sensor is one wire that goes to it. Then +12 IGN, ground, and knock out to the ECM.

Hey, been a while sense posting, yea i should have looked into the Knock filter thing more closely, never heard it called that before..... always called it a ESC Module but thats ok.



But after looking into that and doing some more research, i decided to go with the Holley Stealth Ram TPI style setup. Heard some mixed reviews on the mixture distribution of air/fuel with a N/A motor, but no problems on a forced induction setup, sense im going to be running a turbo.


Another thing that has been boggling my mind is if i can run a TPI/TBI distributor in my vortec block? Or is there any way i can keep the Vortec dizzy and make it work with the EBL???? This has got me so confused, ive heard of people making them work in the TPI's stock form but would hate to confuse the EBL and burn up the ecm or something due to incompatible voltages or it not pulsing the injectors correctly.


Has anyone ever accomplished this or is it even plausible to think it can work?

Help appreciated, Thanks

 

My understanding is that a standard distributor drops right in. The Vortec distributor just being a cam sensor along with the cap & rotor. The crank sensor being at the front in the timing cover.

In the case of the Vortec set up use a 8-pin ICM and it will interface directly to the EBL ECM.
