matt b Posted April 18, 2008 Report Share Posted April 18, 2008 Matt, I'll be heading down past your doorstep on July 2nd on the way to Tampa. Will you be around? I may have a trip pop up between now and then too, but nothing planned.PM'ed you my cell number.I didn't know you could put a T5 ECU into a LPT GLT. Doesn't taking out the ECU disconnect it from +12V and make it not ready anyway? I use to get a CEL for a bad SAS valve, and I'd just pull out the ECU for a minute to get rid of the CEL. I finally got tired of pulling the ECU and replaced the valve! That's what I'm running now, runs like a raped ape. Link to comment Share on other sites More sharing options...
turbomoose Posted April 18, 2008 Report Share Posted April 18, 2008 How cool Matt! My neighbor has a '97 GLT LPT wagon. If we were to go to a salvage yard and get an ECU from a '97 T5, pop it in, would that turn his LPT into a T5?! ...I don't know why I'm getting excited about this. :idiot: Link to comment Share on other sites More sharing options...
matt b Posted April 18, 2008 Report Share Posted April 18, 2008 :lol: Not sure why you're this excited about it either, but it's funny.Basically, I hit the same boost as every T5 on the road but I have a nice low-end torque curve with that engine. IMO, having driven both for a while, I'd rather have a the LPT block-T5 ECU combo than the HPT block-T5 ECU. Link to comment Share on other sites More sharing options...
cheapwagon Posted April 20, 2008 Report Share Posted April 20, 2008 So what boost are you running on the 13g with the T-5 ECU? or did you swap to the 15g also? Link to comment Share on other sites More sharing options...
matt b Posted April 20, 2008 Report Share Posted April 20, 2008 So what boost are you running on the 13g with the T-5 ECU? or did you swap to the 15g also?Gauge is dying, so not quite sure. But after some cleaning of the gauge last night, I saw 12 psi on my 16T. I guess that's what should be expected on this combo. Link to comment Share on other sites More sharing options...

turbomoose Posted April 22, 2008 Report Share Posted April 22, 2008 I'm still unsure about this 'mod'. From what I know, all '97 850 GLT LPT's have SAS. VERY few '97 850 T5's have the SAS. And very few early '98 S70 T5's have SAS. If you take an ECU from a '97 850 T5 without SAS and put it in a GLT LPT with SAS, does that just mean your SAS is ignored, or will it trigger a CEL?

matt b Posted April 22, 2008 Report Share Posted April 22, 2008 so what would you expect from a t5 ecu and a 13g? (still broke from buying the damn car )Very similar results. Honestly, the 16T did not feel THAT much different, the ECU was the biggest difference.I'm still unsure about this 'mod'. From what I know, all '97 850 GLT LPT's have SAS.

You start having CEL's when you cross the EGR gap and try to run a post 95 ECU in a pre 95 car, or vice versa. Link to comment Share on other sites More sharing options...
cheapwagon Posted April 22, 2008 Report Share Posted April 22, 2008 This is way more confusing than I thought it would be. I see T-5 ECU's on here and ebay a lot and I would like to do the swap. I don't care about the CEL because the damn thing has been on since I got it and I just passed emissions so I am good for almost 2 years now. Can EGR and SAS be removed if I get an older ECU and still have the car run properly? I know I have SAS but do I have EGR also? According to V@dis it looks like there were 2 options for the GLT one with and one without. Link to comment Share on other sites More sharing options...

According to V@dis it looks like there were 2 options for the GLT one with and one without.You have SAS or EGR, not both.I am running an ECU from the UK, and my SAS has been unsused since. It is not recognized by that ECU and doesn't trigger a CEL. Run whatever ECU you want if CEL's aren't an issue! Link to comment Share on other sites More sharing options...

Mine has the motronic 4.4 i believe, which came out in 97. I have no idea what that means tho as far as swapping a 4.4 for the 4.3, and the potential ease of adding some hp while my wallet recovers is tempting.

cheapwagon Posted April 23, 2008 Report Share Posted April 23, 2008 I was told the 98 and 97 are not interchangeable. here is the link Link to comment Share on other sites More sharing options...
matt b Posted April 23, 2008 Report Share Posted April 23, 2008 I was told the 98 and 97 are not interchangeable. here is the linkThey are not interchangeable. Gary (Yellow95) has run a 97 ECU in his 98, no issues. But a 98 in a 97 will fry your AC controls, among other things. Link to comment Share on other sites More sharing options...
flaco Posted April 24, 2008 Report Share Posted April 24, 2008 Not true. Ive used a 98 S70 NA ecu in my 96 NA 850 and other than a CEL it worked. Im sure we discussed this a while ago and this is one of those myths floating around....Of course 99 ie motronic 7 is a diff beast. Link to comment Share on other sites More sharing options...

Not saying it won't crank, just saying it'll get warm. Link to comment Share on other sites More sharing options...
