I just Bought a Zr1 Map sensor to upgrade to a 3 bar sensor, I was wondering if anyone knew if there is an adapter for the Ls2 harness to Zr1 sensor or would I have to wire in the Zr1 Pigtail and if what modifications would I need to do to install in place of the Ls2 Map? Also would I be able to monitor boost numbers with the Zr1 Map in HPtuners?


Thanks in advance guys!

Better check to see if your ECU is even compatible with zr1 sensor. I don't believe it is.

If you have a 2005, then that sensor is out.

I believe Caspers and Katech sell adapter harnesses.

I do have a 2006, so would it work with my computer?

The holes are different sizes?

Harness is a bit different.

I used a 2011 ls3 map in my c6 just because my fast already had one in place.

I got a harness adapter off my buddy and just spliced it in..

But I remember the holes being different sizes, and that's why I didn't use the factory piece.

I usually just use a 2.5 bar on the LS2 cars and move to the LS9 sensor on LS3 cars.

LS2 E40 needs a DPE or DSX 2.5 bar sensor. Will not work with the ZR1 sensor tuning wise. Not sure about physical fitment, but that's not the major problem. The problem is the computer literally won't accept the proper data for the ZR1 sensor.

Ask me how I know.

https://www.corvetteforum.com/forums...nsor-pics.html here's a thread about the sensor DPE/DSX use. I ended up making my own, but it's ugly, and was a PITA to do, so I'd probably just buy one if I were doing it over.

Ok, the only reason I got the Zr1 Map is because my tuner did recommend it to me and its 3bar, but your saying it will not work at all on the ls2 with a 2006+ computer? I know I've seen a zr1 sensor with a adapter for a ls2 on http://www.jdpmotorsports.com/genuin...ensor-12592525.


Also would a LS3 Map be more realistic? I also have a FAST 102 if that helps with fitment?



Thanks again for all the info.

Pretty sure the tune will only read to 255kpa (23psi area) so if you have to modify the manifold to use the sensor, it probably isn't worth the effort. If it fits properly, then I suppose it can be used, although wont read full 3 bar.

schpenxel

I was wrong. It must be only 2005's that it won't work on

A 2006 tune will accept 0-512 on the linear value and -256 to +256 on the offset

2005 will only accept 0-256 and 0-256. No negatives and nothing over 256. The ZR1 sensor has a negative offset and linear I think is 300 something. Thus the reason it won't work right on 05's.

Sorry about that. I thought the 06's were the same. This is assuming the three "stock" 2006 files I pulled off the HP Tuners repository are actually from 2006's. No reason to think that they aren't though.

ButtersFRC

Yea I knew that the 2005 and 2006 had a difference in the computers, and for a second you had me doubting myself.

schpenxel

Not sure why I always thought 05 and 06's were the same, then after that they changed. Guess I learned something!

realcanuk

I think 05 is an E40 and an 06 is an E38. Not 100% on that. I know for sure 07 is E38.

schpenxel

I really wish mine had an E38. The logging rates are insane compared to the E40.

And HPT has their VVE support working pretty well now, so that makes it pretty easy to work with

realcanuk

I haven't upgraded HPT to 2.25 yet because its working well and don't want any new issues. I will have to get on that one of these days.

ButtersFRC

So the Zr1 map should let me read boost on HPT?

schpenxel

The new editor is working quite well.. but the new scanner is a steamy pile of dog ****. Histograms don't work live, don't think you can use an external input, etc. Seems they are more concerned with supporting more Ford platforms than making the basics actually work.

And don't even get me started on them STILL not fixing the stand alone logging issue. The latest 2.24 production version and the beta break stand alone logging. It's been broken or over 2 months and they still haven't fixed it.

I've been using the new editor and old scanner but it took some messing around to get Windows to open .hpt in new editor and .hpl in old scanner.

Sorry, rant over, lol.

Should.

ButtersFRC

Thank you! Now just need to find an adapter or pigtail to wire in....

schpenxel

Should be on eBay. I think I have one saved on there somewhere if you can't find it

See if item number 121257485228 is what you're looking for
