Lower than expected boost on a cold day.

[smithy]

Everything has a chance smithy, one mistake by me and the race is yours lol.



I was quite impressed with yours Dave, it pulls hard and felt good to be back in an oblob.

you never know mate you might not need to make a mistake and i might still beat you lol,but when its finished and back on the road i will pop round the shop and give you the keys i think you may be surprised at how the old girl goes now .she is quick at 17 psi cannot wait to turn the old girl up to 28 psi thats when i will give you the keys,so you can get the full benefit.can you still take rwd now you are a 4wd junky lol

I went out in Dave's while she was running full boost... a very rapid run up the M1, preceded by a short, windows down tunnel run.
Very impressed (although, I may have left a little brown mark on the seat lol!)

Obviously within the bounds of the legal speed limit.

I have been trying to track down the funny smell for weeks?!!! Boost leak with follow-through?

[Dangerous Dave]

Boost leak with follow-through?

You can shorten that to "crap boost"

Lol, congestion wouldn't allow any more than a brisk run up to match the speed of the traffic

Propper funny when you asked if I was watching the the Torque app and I replied "No, I was looking for something to hold on to!"

[Wobbly Dave]

Sure made me smile

[wegal]

Now fess up.. was it the speed and acceleration... or wobbles driving ?

After all hes called wobbly for a reason.. and it aint anything to do with his weight !!

[M-R-P]

Tee-hee, not sayin

Haha, mate if its got a wheel in each corner i can drive it, always have been able to RWD @ 28psi, that makes me go all warm and fuzzy inside

Time to 'fess up. We ran Betsy with the calibrated boost gauge & the reading were under - so ultimately no fault or boost leak found - however I am now frustrated by the underread & overread from the same application - hence effing useless. Darn it.

I haven't entirely given up on the application. I have tried both MAF reading the boost too - but the results are still under.

Annoying as the mid November readings were a little bit over.

So Justin - that was her running properly - but the Application not.

[M-R-P]

At least she's running right mate. And you hadn't left the clip loose on the ic hose

so are u saying that electronic gismo is crap in ur car t
hen it looked nice and shiny though and ur car is quick mate ps u still looking at uping the torque on ur car and bhp

I think the software could have issues updating all the overlayed displays. That's a lot of info for a blutooth system to cope with and it may be suffering some sort of lag.
Dave, try reducing the number of dials on screen and see if it becomes more reliable.

I am not saying it is crap - I think it needs work & is not a straight forward as I thought. I presumed (presumption being the mother of all ££££ups) that it read from the MAP sensor. Perhaps Martin is correct - I am running too many PIDs.

I still prefer it to the boost pod gauge horrible things.

I will find a way to make it work.

And yes Smithy - I am still looking at a shed based engine DIY build. I am not planning something OTT to start with just in case it all goes wrong. I think forged rods & volvo pistons to keep the budget down.

Once the bathroom & nusery are finished - I will start looking for a suitable donor engine.

the system looks nice though hope it work mate and the standard volvo piston only go .4 oversize so make sure u get a good block with hardly any wear on it or u will have no choice to go for aftermarket piston witch go to 82m
m bore .i went 97mm bore on the 940 with wisco forged pistons .volvo pistons are good for 400 bhp though aslong as the map is good witch will be with hlm doing it

[Wobbly Dave]

I am still undecided about wiseco pistons or volvo oem - as this will be my first rebuild. I may just leave the original pistons in & just drop in some rods - then when it all goes wrong I will be not crying so much.

Hamish was talking about a possible trip to Sweden - to get it remapped.

Cooorrr Blimey! and there I was, working out how much it would cost in fuel to get to Bromsgrove! lol

[M-R-P]

I just thought about something else... Are you using the app under the same circumstances? i.e. start the app with the car off, or start the engine then start the app or even start the app when moving? there may be a calibration problem if the software looks for differences in readings, rather than calculating the physical value of the reading.
I think I made sense

[Wobbly Dave]

I have been doing some reading around & there is a way to make the boost readings more accurate in TORQUE.

You can make subtle adjustments for the MAP sensor in the car profile. I have been trying to also find a good value for the volumetric efficiency. I was using the standard value.

I am hoping that Adam will call me soon - as I need to finalise things like the baud rate from the ME7 ecu & see if there are subtle differences in the PIDs that Volvo ECU is reading vs what the app is trying to use.

I think with a bit of final tweaking I can get this right. I don't know if the ECU makes allowances for changes in barometric pressure. This may go so way to explaining the changes due to temp & height above sea level.
