boost problems

[big_fletch]

Yer mate, i have done alot of playing around with my Boost settings and have finally got them where i like.. When boost is at 15psi or more for longer than a couple of seconds it shuts your throttle pedal down as a saftey measure. I will be installing a small voltage modifier to prevent this and run 16psi constant on my high boost setting. Currently using low boost around town of about 9psi Max which helps fuel economy massively lol

thanks, backed the dawes off [screwed out] and boost went through the roof again, now its at a spot where atleast its drivable, just............ What happens with the hose coming out of airbox, have dawes going to centre of vac solenoid and other 2 looped off,. are dawes that touchy? need to find answer.


Update, now I know whats what I re did the dawes as per Chazs" drawing, now all three vac tubes are fitted per pic to vac solenoid, now it drives great max boost 15psi. EGTs rise and fall with driving style,,,,,,,BUT still spikes but only to 15psi and only when the speed levels out, getting the needle valve next week but not sure if it will fix spike

I may have the answer to your problem I think lol.. You say the vac line from the dawes goes to the boost solenoid and the other 2 looped off?? Where abouts are they looped off to??

TO block the solenoid

Gotta give BIG FLETCH 2 thumbs up, he took the time to ring me and confirm my layout. like I said best forum on the PLANET, could edit that later to UNIVERSE, but thanks again BIG FLETCH no doubt we'll catch up next fishing trip.

Stay tuned as DIESEL SMART are sending me a module to plug onto the air flow meter and a oneway valve for the vac pump line, claims of up to 130Ks a tank achievable, excited by this.

Im also interested to know more about this Diesel Smart Module? Sounds good if it does what they say lol

Wil PM you with info

Here's the latest, I've Fitted The DIESEL SMART module that piggy backs onto the MAF sensor, and oneway valve that goes to the vac pump. All vac and boost lines plumbed as per DIESEL SMART drawing, very easy to follow. Boost still needs adjusting to 18-20 psi, which I hope to do today if it stops raining. Boost at present is 15ish. truck drives great, very impressed so far. must admit the DAWES is a touchy thing and as suggested to me I"M not going to stretch the spring, I'm putting small S/S washers in to increase the boost. [great having mates who work at the airport for Qmart]. Nearly there just the fine tuning to get it perfect.
