New ecm ideas?

[Syclone#892]

So i know there are a lot of people trying to make the coil on plug setup work on our trucks. That would make things a little nicer on the truck along with having the ostrich to tune it quicker/easier.

Well I have been thinking this over and just wonder if it would be possible, I'm looking to hear from the syty nuts who know a lot about our current setup.
Do you think it would be possible to adapt the pcm from a gtp to our trucks? Yes I see wiring could be an issue but thats all I can really think of. You can use hptuners to tune everything and it to me is a better ecm. As far as I know it does everything our ecm does just better and more options plus to me an easier setup for tuning.

I have a spare gtp pcm and a wire harness off the fiancee's totaled gt that I could possibly make work so I was just wondering what some people thought of something like this.

My reason for thinking about this is efi connections kit that makes the ls1 pcm usable on lt1s and old school small blocks. I asked if they could possibly make something work on our trucks but they said there isn't a v6 pcm program for those pcms and they just don't have the time to research it.

I have also been checking out the gtp forum and found this nice gt

He used to run 8.65 with twins and now he wanted to make it more streetable/driveable so he switched to a single turbo and redid a lot of stuff. They put it on the dyno and gave it a rough tune to 720ish horsepower then took it to the track for an event they were having and the shakedown run was a 9.25 and the second was a 9.10
I just think its crazy they can be so much more ahead of us!

So who thinks this might be possible? Thanks for any info

You can search here for 'DIS', and also visit the Code59 forum.... there's a lot of things being discussed over there
http://www.code59.org/
Once again, just search around and you'll find some threads on both sites.

Re: New ecm ideas?

Yup I know about the search
I currently have ls1 coils on the truck but have a problem using a crank trigger with my current setup. Once I have time I should be able to make it usable but so far no time

I was just thinking outside the box and like I said I think hp tuners might be a better setup than using an ostrich, chip adapter etc especially seeing how many issues aeroking is having.

Thats all for now :tup:

I'm pretty sure RPM has a new crank trigger system.. maybe check it out.

Are you sure?? :roll:

EFI Conn. did make a custom harness for a TY using a 411 PCM, but he said there was no money in it to make them for V6 apps.

Do the GTP ECM's work off of speed density or MAF??

Re: New ecm ideas?

Rpm crank trigger is made of the same design as the one I currently have, an older msd kit thats not made anymore.

Reason it will not work on mine is my billet specialties tru trac belt setup. Billet specialties said they know its very difficult to make it work with there setup. If I had twin turbos it would be a lot easier as the crossover pipe would not be in the way, but currently the lower rad hose, crossover pipe, belt mounting brackets and ps pump are in the way I have finally come up with a design where I make a new bracket for the sensor and custom mount it it just wouldn't give me any adjustment.


And yup I do know how to use search you just have a leg up on my because you made that post. If you type efi connections into the search that post does not come up

Plus i was asking about a gtp pcm which may be a 0411 I just didn't know cause I haven't looked that far into any of this yet thus this post.

Anyway is the pcm you are talking about the v6 s-10 one? Have you gotten your setup running?, Gtp's are maf based.
I am fine with doing wiring and figuring out where things need to go I just don't want to invest a bunch of $ without knowing if I am wasting my time and figured I would check to see if this would be possible.
I will be honest I was thinking about this on the way home from work driving my gtp so I have done zero research on this. I was just posting this to get a start on a possible future project

I do like you idea better though although I would need to buy things rather than use what I have laying around. I have thought about the gm vortec timing cover/crank sensor/ reluctor wheel setup for a while just didn't know if it would give the signal I need currently like a crank trigger would. But if i use that pcm I wouldn't need to worry about the signal as its all designed to work together.

Its funny also because when I talked to efi connection they kinda just blew me off and said they have a sy there that they would like to do something like that one but don't have the time and the ls pcms wouldn't work for them, they never mentioned making a custom harness months ago. Oh well.

Thanks for the info now I got some more things to research and think about

Re: New ecm ideas?

My search was under “ PCM” not EFI Connection.

Some shops are busy and do not have the time to shoot the $hit. EFI C did make a 411 harness for a tuner in the Midwest and that tuner ( I talked to ) did get a Typhoon running and claimed it made 450HP although I believe it had an after market hair dryer on it.

I am (hopefully ) days away from starting my truck with the 411 PCM. Although it was done half assed (old motor in newer truck) but there is another lad (Poconojoe) doing to his Syclone, so he can offer specifics to his app. For what I did at least 2/3 of the harness connectors stay the same. Others had to be retrofitted to the older connector style. (just the connector –the wires are ok)

We were aware about the dual sync distributor, but unfortunately the manufacturer and just about everyone else was clueless about V6 application as well as the signal it generates. It would have been a simpler approach, but the unknown support was not worth it. :tdown: You do need to upgrade to a newer dizzy with the cam signal output as well as the crank sensor (seen in my other post)

So yes, - it is the 411 PCM used in the V6 and V8 GM engines. I am curious as to what the Pontiacs used since I am curious to what they did for a boost signal (MAP ?) Granted supercharged apps are limited to output by the pulley size whereas turbos will keep boosting.

If the Pontiacs use the 411 we would be interested in looking at the factory .bin file for the supercharged engines.

Here is what Mike @ EFI Connection sent me when was e-mailing him last year: If someone got a group purchase going EFI Connection may make harnesses? Although Mike said at the time they are busy with V8 products. If there were enough people interested they may be swayed to make them. Could not hurt to ask.

Re: New ecm ideas?

To use the 3800 series II PCM, you'd need to replicate the fast-start crank sensor arrangement, and then a cam sensor. You could probably modify the late 4.3 sensor to work. You'd need to add a MAF as well.

Could be done. Doug seems to have a pretty good leg up on the '411.

I always had a crazy idea in the back of my head to use the ECU from the early 90s Ultras with the blower and MAF. They're sequential ECMs.

He used to run 8.65 with twins and now he wanted to make it more streetable/driveable so he switched to a single turbo and redid a lot of stuff. They put it on the dyno and gave it a rough tune to 720ish horsepower then took it to the track for an event they were having and the shakedown run was a 9.25 and the second was a 9.10

Why is it that you think that car is so much more ahead of us? It's pretty much a full-tilt race car.
It weighs 2300#, has a tube front end, a very heavy built 3.8. It's a race GN, with a sideways motor.

Which is not to detract anything from the car- 8 second passes are awesome. But given enough $$ and ambition, you can make anything run whatever number you like. Compare that car to Robert's Sy, and you have a pretty fair comparison. Not that far off, when you look at it.
