Any ME7 custom tuners out there ?

I bought the 2000 Moondust S70 last fall with a bad engine. I normally wouldnt do that but the car was in such great condition. A person on Swede speed suggested i replace it with a T5 engine. I sourced a low mileage T5 from a 01 S60. The swap went great but after about 90 miles a CEL popped up. VIDA shows fuel trim error lower limit. I basically replaced all hoses during the swap so im sure i dont have a Vac leak.When the cell pops up the car runs like its a N/A S70. When i reset the ECU the turbo spools up but dosent pull any thing close to my 01 T5 S60. Im thinking the ECU dosen't like the bigger turbo and injectors. I exchanged emails with Ken from IPD and he dosent have any options. I also spoke with Aaron at VAST tuning and he only tunes up to 98 P80's. I called a few specialty shops in Denver and IL. and they couldnt help me either. Both Ken and Aaron suggested i put the brown/orange injectors back. That didnt help either CEL returned after 190 miles driven. I have heard about a guy in CT named StevO that can custom tune the ME7. I cant get any contact info from him (if anyone has it pls PM me). Do you guys know of anyone out there that could remap my ECU to play nice with the T5 engine ? Needless to say i will need to pass emissions next fall, but would really like to take advantage of the T5 assets. This car was supposed to be Dad's sleeper sedan. Now it runs like Grampas 3 cylinder Yugo. Thanks for reading !

Just had a great tuning experience with Hilton Tuning. Send him an email and ask your questions, should be able to sort you out!

+1, I highly recommend Hilton. Aside from a low boost issue, my tune from him has been solid. The problems with my car are strictly my fault!

SteveO does ME7 as well, he works out of Rolling Motors in CT. However he mainly works with Volvo owners local to his area so he can do a more personalized tune (he can dyno test and monitor the car as he's tuning). I haven't worked with him (CT is a long drive!) but he has a great reputation for solid tunes.
I believe he's on Swedespeed, you can probably message him there. You could also call or email Ben McNally, he owns Rolling Motors. https://www.facebook.com/RollingMotorsLLC/

I dont know anything about this, but I would put larger injectors in like many the green, and change the ox sensor before I started tuning. This seems like a minor imbalance easily corrected thats keeping the computer from allowing boost. going down to the red is the wrong direction to correct lean trim. I would start with the ox sensor and put the original injectors back.

I appreciate the comments and suggestions. As far as O2 sensors,,,, are you saying put in brand new ones such as OEM/Bosch ? Or is there a specific upgraded O2 sensor that i should be looking at ?

These cars behave best with OEM Bosch sensors. Personally, I wouldn't replace them unless there's an issue, but depending on the mileage, you may want to replace the upstream sensor just to be sure that it's as accurate as possible for the ECU.

its possible the computer just thinks the trim is lean due to the ox sensor no.1. sensor 2 is only to protect the cat If sensor 1 is bad. Its worth a try putting a new Bosch in. and put back the brown injectors if thats what was in there to begin with. The order of delivery is red white brown green in increasing order if I remember right. later you can measure fuel pressure which could be low due to relief valve or plumbing leaks in the tank etc.

also, the t5 may have a higher volume pump.

Post by **bmdubya1198** » 21 Jun 2019, 19:15

The pump in the T5 and LPT should be the same, but a different injector will require a different tune. You can't just swap around injectors without having it tuned. Blue or green injectors on an LPT tune will cause it to run rich.

The injectors in these cars (for turbo, at least) are red/orange for LPT and '94-'97 Turbo/T5, white for '98 T5, blue for 99+ T5, and green for 2000 R as well as P2R models. Brown injectors are for NA models, I believe.

A bit off topic but ...

Oranges are 315 cc/min and shipped in HPT cars 94-97 (T5 850)
Reds are 315 /min and shipped in LPT cars (97 850 GLT, S/V/C70 GLT)

I have been wondering and haven't seen it anywhere - are reds and oranges truly interchangeable? Are the dead times the same?
