Hi guys
right in the middle of putting a standalone ecu in. Using LS1 coils, cam sensor for sequential ignition/injection.
At this stage we are trying to incorporate the motronic for some other functions relating to obc ( not sure how successful weÂ’ll be) and using haltech 750 elite to control fuel spark
Does anyone know how ill get my cruise control to work post conversion? I understand there is a seperate cruise module, but as I am using a different TPS, the original sensor wonÂ’t work
Im a bit confused with this, any help much appreciated

Are you using a different throttle body all together?
Im imagining some sort of splice or wire tap off the new TPS that would *hopefully* give the cruise control unit its information?

Ok, thanks mate
im pretty confident the ecu isn’t involved in cruise control on our cars. Is someone able to confirm this? As long as I can set the tps up to talk to the cruise control module? I really need cruise as it’s my daily and I often drive interstate here in Australia, so long distances
Any other ideas?
Check out pages 6710-1, the "CRUISE CONTROL ACTUATOR" box shows "FEEDBACK POTENTIOMETER" on left side of box.
The oem TBS is a potentiometer and must feed this.

The tuners are putting a Haltech in my car as we speak and said they had to change the TPS. Guess I'll have to tell them to make sure the cruise & OBC works.
When they came up with a solution, I'll let you know.
Or if you find out first, let me know so I can educate them.
For what there're charging, they better have a solution.

Hi Bob
That’s funny you’re doing the same as myself!!
Yep, def need new tps. I bought mine from e28 goodies and I think it’s from an e36?? I shouldn’t think it would be hard to get cruise working...famous last words 😲
Here's the pin out for Motronics. E28 535i should be the same as our 6's.

Here's the ETM page 1360-1 shows TPS input that I think feeds to cruise.
http://wedophones.com/Manuals/BMW/19...g%20Manual.pdf
This is the TPS for a B35 and I had one with the B35 intake i bought. Used the B34 TPS and sold the B35 TPS.

How stupid was that. The tuners bought a TPS but I don't know if it will feed the info correctly
Then there's the OBC to worry about--DAMN hole just keeps on getting deeper.
Just more info if needed.

Ok
I can confirm that my cruise works!!
After wiring up the ecu, base tune works well to drive to the tuners.
Currently on the dyno with a haltech specialist, so will have more to report
First impressions are very good...
I’ll post links to videos and pics next week. Cruise was a big unknown to me but it’s apparent that it is independent of the motronic.
Hope this helps someone else as I couldn’t get any definitive answers before.
Good to know about the cruise.
Did you get OBC to wotk?
No
I think it could be made to work with a clued up auto electrician as I have the wiring diagrams. Not sure I could be bothered to be honest.
As this is my daily, I drive an hour to work through highways so cruise is used regularly.
Just spoke to my tuner and he’s going for a conservative Street map which is what I want. Get my first drive in it tomorrow which is exciting as it’s been off the road for 3 months.
If anyone is interested, I’ll post some videos and pics of the setup. Looks really good without that big air meter, and 6 LS1 coils!!
I'm just wondering, why did you do the conversion?
Great news, enjoy the maiden voyage.
Yes,yes post pics & videos. I blew the head gasket on mine June 2018.
Rebuilt the engine with B35 Hartge head, custom pistons, headers and a bunch
of other goodies with Haltech stand alone. At the tuners now. They take their sweet time,
hope to get it back by January. That makes it a year and a half project just for the engine upgrade.
Geez that's a long time to wait. Will I smile when it's done?

Hi Anri
i used an elite 750. It has everything you need for bringing an older engine into the 21st century
Sooo much easier to tune than my MegaSquirt I used on the Porsche. My mate and I dicked around for months tuning that thing, the haltech was seamless right from the start. Simple base tune and it fired beautifully. Sequential injection and ignition...I’m actually getting decent fuel economy!!
Check out this video, it’s the same one I’m using

Anri,
I don't know- I let the tuners chose the model I know nothing about stand alones.
It was water getting into cylinder #1.= while @ WGI. Never overheated.
It shouldn't happen again with a complete rebuild and in the 31 years I've owned this 6
it never ran hot.
Hi,
Okay I see. Lets see what they will come up. To put
M30 on Coil on Plug (cop) will be a challenge due to
spark plug location. External cop will be the direction
for M30 if you want to make it to sequential. Or there
is another and cheaper approach leaving the system
factory stock and pair 3 and 3 injectors.
I have done 5) S38s Haltech Stand-Alones system.
It's a big project, as everything else with these engines
if one wants to make them little more modern
Hydro lock will cause damage quickly.
Regards,
Anri

I’d be really interested in what the notes are/were on the s38 engines. One day I hope to look into it. Just read your other post. Might be best to keep stock except exhaust and cams and pistons.

Hi,
Yes we have a kit Jumper Harness made for S38-B36 and
S38 B35 and S38 B38. The results I achieved are great
and the pleasure and the fun from this is priceless.
Stand alone on a stock engine is absolute not worth it.
But, if you can install cams and exhaust system its all
worth it.
For example the concentration using stand-alone on my
daily driver is not to make power but to achieve best
mpg. I will be pushing nearly 30mpg. I will not be making
power at all because I will retain the small cams 264/248
and oem exhaust system.
I am working on another special project but I am not done
yet and that will require some testing before I release.
Fun times. One just need to spent the money.

This beauty is on Haltech. I installed cams, custom timing,
larger injectors, larger intake plenum, M88 headers, hi flow
exhaust. It made 292rwhp that is 344hp at the crank. Rest
is all stock, never opened engine with 60k miles.
A proper ingredients are must, rather than just throwing
parts in. I know people who spent $20-$25k on those special
Strokers !!! yes the 3.9s and never made pass 300 wheel
hp...
Regards,
Anri

Hi Pfitz911,
I don't like Megasquirt. A lot of people have a lot of issues
with...and it's one big headache.
750 is great choice and as Haltech states, lower budget in
mind.
Regards,
Anri.

I already have the cams and euro headers. 11:1 or so is a given

Now that I've got an I.T guy working on my Megasquirt I have no issues. Normally, engine tuners know just enough (no disrespect there). Most times this is not enough to tune with Megasquirt as there is so much you can do with it. Yes it is complex. People think it is stupid and that's why there are issues. No, it is far more complex than other ECU's allowing far better final tunes but, you have got to know your stuff. There is also a lot of BS out there. I had one tuner, someone who sells Haltech, spend 5 days trying to tune my car with the Megasquirt. My Megasquirt guy Aaron has tuned just 5 previous cars. When he went onto the program he saw that the Haltech guy had programmed the injectors to squirt twice, had an AFR of 10:1 and had the engine capacity out by 0.8 of a litre. All of this stuffed the tune. This is a leading Haltech tuner with a specialist rolling road workshop. And he got all of that wrong.
Additionally, I was pressured to buy a Haltech as I was told that the Megasquirt does not have an autotune. But it does. We will shortly be driving my car with Aaron and his note book next to me while the megasquirt self tunes the engine up and down the rev range and in all gears. Again everyone else says this feature does not exist.
So, if you are not an I.T wiz who can wire your own loom, stick to Haltech or the others. They ARE great ECU's. If you are an I.T geek, know your looms and want to fine tune every facet of your engine, to the last .01%, Megasquirt is a perfect tool for this.

I agree Josh
You’re using a MS3 as I recall
Better than my MS2
I was on the Porsche forums while i set this up, and there were a few wankers bagging megasquirt, but for an old school engine it’s fine
I was just amazed how the experience was easier with haltech. Maybe it’s because it’s the second time around for me?
Dunno 🤷*♂️
I will say that the support you get from haltech is awesome. Nothing is too hard.
