Anyone try pro efi or motec looking for input on any experiance good or bad on using these units

 

[Siapattack]

I ordered the motec, can't remember what model. But it's the one for the gen 5..... And I have Gen 2

 

[Goggles Pizano]

Motec been used on Vipers just $$$ so people go different root.

I think I heard people using pro efi.

AEM Infinity has a Viper specific unit we developed on the Gen 4's years ago. I believe its applies to all Gens.

Hey Dan,

If I recall, the AEM Infinity-10 has been discontinued for a while now due to ongoing QC issues... much like the 1500U's of yester-year.


To the OP, for a G4 application my suggestion would be Pectel or Motec. To this day, I believe the Pectel SQ6M12 & MQ12 were the only controllers capable of running a Gen-4 without a single extra accessory box of some type. All other options require Wideband expanders, Ignition modules or drivers, Drive-By-Wire expanders, or similar... even the Infinity and Motec options did/do as they are all TTL based ignition outputs and/or dont have internal lambda drivers.

All that said, the Motec M1 series is a great option as well, and would be easier to find someone familiar as its far more common than Pectel.

What about Haltech?

Nothing "wrong" with HalTech, provided it is capable of running an odd-fire engine. But an ECU is only as powerful as its hardware quality and software. HalTech is just *now* getting close to the capabilities of Pectel in 2005. That should put it into perspective when comparing professional motorsports electronics vs standard aftermarket level equipment.

What about us poor Gen1's?

 

[Dan Cragin]

We can still calibrate the Factory 1992-1995 SBEC and 1996 JTEC Gen 1 controller for most any non-boosted applications if helpful.

FYI, back in the day we had great luck with Pectel (like Dan mentioned) and the traction control system worked really well.

 

[FST SNAKE]

I ran a ProEFI system when I drove Blucifer to 252 MPH in 2020 and it worked great. I switched to a Motec system for the next attempt because the tuner is able to control so much more. If anyone has any interest I still have the ProEFI complete with the harness to piggyback off the Gen 3 ECU. I also have a spare new/never used ProEFI ECU. I was about 1400 WHP with that system and it worked great for that. Thanks, David

Calibrate? Are you tuning Gen 1 controllers?

 

[Dan Cragin]

Yes,
We have been tuning the SBEC controller for many years and believe we are the only ones who do so. Back in the day we had a package with a tune that made an honest 600hp and passed Ca emissions.

^^^This is the sort of thing that set Dan's shop apart from just about any other in the United States.^^^

 

[Viper Specialty]

Yes,

I also have the ability to alter G1 code, but primarily stick to prom duplication for repair work as I dont deal with G1 cals enough to be familiar to the point its economical. I refer all the G1 calibration requests over to you guys.

That said... if in the future there was ever some kind of a G1 calibration call in any kind of quantity, I would certainly be interested in working with you guys; I can supply the reman G1 controllers ready to rock with a watersealed and fully potted replaceable PROM socket and RF cover, and you guys handle the cal work. In the very near future I will be able to laser metal sheet & plate on an industrial scale, and making replacement RF shields for the app that are integrated with the potting would be easy at that point.

Secondarily, it is feasible to integrate a programming hub into the module itself that would allow prom flashing while installed.

I fear there is not enough funding/volume of scale to justify... but it is theoretically possible with my existing equipment.

 

[Dan Cragin]

Thanks so much Dan, much appreciated. Most people do not understand that the electronics on these early models simply “time out”.
Also It’s good that the Gen 1 folks know they have the same tuning solutions as the later models.

 

[pokeyl]

Haltech R5 is installed and at the tunner. Should be back this weekend. I did the install.

 

[pokeyl]

Not back yet, Turns out Haltech R5 has no support for waisted spark. Thats after an hour on line with Haltech USA tech support. Ordered Smart coils.

 

[pokeyl]

Coils are mounted.

Nice. I have that same catch can. It works stupidly well for being so cheap.

Last hardware update, I Hope. Haltech MAP sensor.

How far out does someone have to plan to get in for such programming?

 

[pokeyl]

Update, I have this Intake and Exhaust. Heads come off the car next week. Hope the pistons are OK.

"According to technical findings from Chicago Engines, normal combustion temperatures sit around 2,500°F, but abnormal combustion can spike temperatures up to 5,000°F and double or triple cylinder pressures. This massive thermal overload weakens the valve material until the center pulls through and the outer edges curl upward."

 

[pokeyl]

All looked good, but #10.

Going back together.

1. What is the solid state relay sitting on the inner fender running...? Virtually none of those are decently waterproofed, and thats a failure looking for a place to happen. I can recommend some true motorsports versions if I know what its doing.

2. Also, since it seems you are putting some money into things, be aware of those HS rockers. They are fine for near stock and mild apps, but if you have heavy springs and/or port work, they are known for resulting in cracked rocker stands. If any of those things apply, switch to shaft mount.

3. Note that your SS braided lines on the passenger side look to be in contact. IMHO SS Braid *needs* to be fully covered with a nylon covering. It will destroy everything it touches under the hood... including each other as they will saw right through over time.

We made these mistakes decades ago so you dont have to!

 

[pokeyl]

Thanks, will do.
