P369256A Blue ECU.. Is it the old race one??

[4406brl]

Is this ECU the old Blue w/ Gold heat sink the Race one or not??? The Old Mopar book said it was Nascar or Super Stock race ECU.. Thx.

@HALIFAXHOPS will know about that one.

Yes race only not sure what ballast though. Prob the .25 one definatekty not for daiy driving.

I tried it on the street for a few weeks

"May bee used with standard coil / ballast to 7000 Rpm’s"

I couldn’t get my 383/432 to 7000 Rpm’s so I took it off

LOL

Used a Factory .5 OHM Ballast - Tried two different coils , low ohm and standard

I can keep it simple - It’s not designed for street use / Cruise / Idle

Hops nailed it

 

[HALIFAXHOPS]

There is a reason they are "race only" with a low ohm ballast they get hot because they are doing what they are made for output wise and cool off between runs. The larger the ballast the lower the RPM it will achieve. One reason the chrome boxes get slammed all the time they are running a 1 ohm ballast alotso break up at high RPM.

This is the best street ECU I have tested

Idle thru 5500 RPMs

Chrysler 4111850

That was Mopars workhorse there. Then the Older orang box which are crap today they are "authorized" or "replaces" IE China

I have an older orange box that is marked "MADE IN USA"

I'll have to check the part number on it

 

[HALIFAXHOPS]

See if it says anything on the sticker and if it has a real transistor or not.

[Bee1971]

You want ones like this with Stamped Numbers Part Numbers - Chrysler Stamp

 

[HALIFAXHOPS]

Usually. But some of the "authorised by" ones have that also. That link I posted nails real from fake.

Authorized by is usually a sticker , not a Chrysler Stamp from what I have seen

Fake transistors are easy to see

 

[HALIFAXHOPS]

I have seen them with both. Hard to navigate them. The transistor hight pretty much nails if it is real as in old.

 

[HALIFAXHOPS]

 

[HALIFAXHOPS]

Looking for a pic of one. Figures cant find one. The worst are in the moapr authorized dist kits half fail out of the box or shortly afterwards.

 

[HALIFAXHOPS]

these are about as misleading as you can get

 

[Bee1971]

Yes fake transistor with no heat sink under

And no Chrysler stamping

Are those the NEW Mopar Performance ECU s ?

 

[HALIFAXHOPS]

Yup usually burried in the potting so they overheat. we beat the crap out of all of them in this thread.
1974 Brain Box saves the day.

Yes the ones in the authorized kits and some vendros.
