i have a buddy wants me to tune his Tune Port he swapped into a mid 80s pickup. The doner was a 1986 TPI 305 car, wich was the 1227165 ecm and the $32 byte ID. I already have a tunercat definition for the $6E for a 89 TPI.
Anyone see any reasons I can't just load the $6E code onto his memcal and run with it? Freescan will support the $6E which solves another problem with using the $32.
thanks
Brendan.

Just disconnect the 9th injector relay at a minimum.
Sometimes you have to tweak the crank fuel tables.
The 6E appears at first glance to be leaner than the 32. Do a compare on the relavent tables and you'll see what I mean. But plenty of people have just swapped the bin only....
TunerPro is frequently tested on 6E also....
Got any info/links on the LQ4 timing signals. Crank and Cam?

No not at the moment, since I sold the 6.0L I have not been up to date on the latest developement of spark control on these engines, I am however aquiring a 5.3L in the next few weeks that I plan to swap into a Mustang with a turbo, so I may investigate it some more.
I heard that Parish over on ls1tech is running the stock coils with megasquirt now, but I have not seen any info on what he did exactly.
I was wondering what the differences are between the $32b and $6e? I know that the 89 had the 9th injector removed? Is there any other advantage to using the 1989 $6e from a tuning stand point?

Also note that you'll need to disable VATS in the $6E bin in order to start the truck.
Let me see if I get this right the $6e has a sample rate of 10 hz and the $32 has a sample rate of 0.66 hz? Wouldnt that be a big advantage to stay with the $32?
10 hz = a sample is spit out once every 100ms (10 samples per second)
0.66 hz = a sample is spit out every 1500ms (one sample every 1.5 seconds)
If you prefer exteremely slow ALDL data rates, then staying with $32 might be better for you. I have no idea why someone would prefer the incredibly slow data rate over the faster data rate, however.
I am sorry I am new to the DIY prom stuff. But I thought the TBI and 85 TPI ($1F, $4D, $61) had the low baud rate, and the $6e and $32,$32b had the same higher baud rate. Am I wrong on that? are the pre-89 TPI all the low baud rate?
$32 is 160 baud only. 6E is hybrid (160 baud and 8192). I had previously thought that $32B was 160 only, however others are saying that they can connect at 8192 using Datamaster. I am, however, unsure if Datamaster is doing something special to connect at the higher rate or if it is a genuine feature of $32B. I have not yet tested it myself.
