Dmsee Posted November 7, 2008 Report Share Posted November 7, 2008 can you please explain more. i'd really like to understand better how your car changed. i dont have a turbo gauge myself.on my car i feel the turbo needs lots of time to spool up - annoying at low rpm but after 2500-3000 rpm it goes really strong. i guess that's normal for the big turbos on s60, that's the character pf the car, different from a LPT. do i understand right that your turbo kicks in earlier? i'd love that on my car. any downsides at higher rpm?hey, why IPD does not write explicitly about this. i got the impression their TCV is just more durable than the OEM but does not change your engine working in any way. thanks for your thoughts!Basically boost comes much smoother and earlier Before lets say you shift at 2500rpm if you had a gauge you would see that it would be somewhere around 0-5 psi with ipd tcv boost is already rushing towards 10psi Gas pedal is more responsive towards boost (1/4 throttle and there is boost already forming )Hope that explains it Link to comment Share on other sites More sharing options...
tgrjmp Posted November 23, 2008 Report Share Posted November 23, 2008 My Solenoid TCV broke as the old '95 plastic got brittle, I purchased a replacement and swapped it out at the same time as I Upgraded to IPD ECU. Great improvement but my gas mileage went way down so before blaming IPD I glued the old Volvo TCV back together and I was happy as the performance went up and got 20 Mi/gal.Lucky from IPD told me that the IPD TCV did not work on the 855 so I finally researched around and found several pages on the ACDelco 214-474, made reference to 850s and V70s.http://www.v70r.com/forums/index.php?autoc...ticle&id=55So I went out and purchased the connectors from Ballengerhttp://www.bmotorsports.com/shop/product_i...roducts_id/1010 $4.99 + shippinghttp://www.bmotorsports.com/shop/product_i...products_id/570 $4.25 + shippingPurchased the 214-474 for $30 with shipping.A few inches of wire for the converter harness... I crimped and soldered the connectors.I am using Silicone hose since the old rubber ones also got brittle.I performed the ECU reprogramming as IPD recommends for the HDTVC and went out for a spin.WOW.. new found power on the low end and also on the top end... My 855 sleeper woke up on I95, now it is costing me a lot more to sell it. Runs great but not as great as my v70R Manual 6 speed.since I purchased 2 sets of connectors I will purchase another GM ACDelco solenoid and test it on the v70R.

db130 Posted November 24, 2008 Report Share Posted November 24, 2008 Glad to see another DoD(Disciple of Delco) on board. As the <cough>creative genius</cough> who came up with the Delco idea, I welcome you all. Link to comment Share on other sites More sharing options...

tgrjmp Posted November 24, 2008 Report Share Posted November 24, 2008 I have a AC Delco Tcv... whats this reprogramming?From IPD website:"Volvo engine control units feature ‘learning’ software, this means the on board programmed logic inthe ECU can adapt to changing conditions in certain engine parameters." Perform the procedure on the instruction sheet so the ECU adapts to the changes. I liked the mod boost comes much smoother and earlier. Link to comment Share on other sites More sharing options...
pangster Posted November 24, 2008 Report Share Posted November 24, 2008 I've got my IPD HD TCV sat here - going to hopefully get around to fitting it this weekend as I've now completed a Stage 0 and full service on my car! B) Link to comment Share on other sites More sharing options...

Cal3thousand Posted November 26, 2008 Report Share Posted November 26, 2008 Just found a cheaper place that carries the solenoid:oehq.com search using PN#: 1997152price at time of posting: $21.80 Link to comment Share on other sites More sharing options...
pangster Posted November 30, 2008 Report Share Posted November 30, 2008 I got round to fitting my IPD HD TCV today and can only echo some of the comments already said in this thread r.e. it seems a lot smoother and more stable than before.. overall pretty impressed with it (although to be fair - I would say that my stock BCS had seen better days so not sure what difference you would notice against a stock BCS in good condition) - either way I know I shouldn't need to replace it any time soon! :) Link to comment Share on other sites More sharing options...
