Racetronix offers a double pumper now?

If running 2 pumps and you only want the one to kick on under boost, get one for 2-4 psi

No gonna modify a double

Looking for a 99+ ls1 411 pcm. Seems my 98 pcm wont operate a 4L80e? Dont want manual valve body. What are stock 99 and newer pcms running? Lmk

Just cause you can't segment a 98 doesn't mean it won't shift a 80

I dont understand. Every where I read they say I need a stand alone or manual valvebody

No. You can use a couple relays to reverse the shift solenoid pattern or frost makes a plug n play harness .
From what I remember the 411 doesn't even need segmented but

PM Slow67 on LS1tech - he has a diagram for relay mod. Don't know what he charges if anything.

I did the segment on mine as I didn't have any of the wiring.

That being said the 411 will be better for S/D boost tuning - the older pcm has some limitations on the V/E tables.

I have a 99' PCM from the orange Z28. Let me know if you need it, I'll make a great deal for you!

HPT has the 2 bar tuning for the 97-98 PCM. I think it costs around $200 with HPT to do the custom OS. $100 to license the VIN, $100 for the custom OS. I don't think EFIlive has a custom OS for the 97-98 ECM (stock ECM is free w/ EFIlive)

I have repined a 4L80 harness to 4L60 in the Impala build. Simple pin swap IIRC. Will need a segment swap in the tune.

Quick update. Bought jonnys 99 ecm, got my dual fuel pumps and racetronix kit, dave gave me a hobbs switch that I still havent picked up. Bought jeremys 80e and am waiting to rebuild it and order a stall. Nothing but the 5.3 and intercooler are installed. Bought a new house and have had project after project that takes priority over the firebird. Actually right now though im in the process of building a 30x40x10 polebarn just for the firebird. So a lot of funds and time are here. I still plan on finishing and enjoying it this season but not yet. Pouring concrete monday, trusses going up this weekend. Hopefully start on it again after the 4th. Still need wastegate and injectors

I've got an XS Power 44mm gate I'd sell you if you're interested. Has about 200 miles on it.
