Got my new solenoid in the mail today. Installed it, and what do ya know, the pcm correctly controls boost. I still have the 10k resistor inline with the MAP, so it makes about 2.5psi more everywhere than it should, but thats ok. Means an absolute peak of 9.5psi, 3rd gear WOT at 2500rpm. after...
I guess as an aside to this, if some of the more experienced tuners want to post some of their custom BINs, that would be great. I'd like to see the changes they make.
I decided to exercise my Google-fu. I've been thinking this information had to be out there somewhere, that Wester's Garage can't be the only game in town for do-it-yourself 94-95 6.5 programming.
After some digging around on this, and and 20 other Diesel, tuning and DIY EFI forums I came up...
And that solution will be implemented around the time I swap on a different turbo (like an hx40). I just drive 5 miles back and forth to work 99% of the time. I live in Florida, so there are not even hills on the way. Stock control, with a boost fooler to up everything about 2.5 psi will be just...
I've been driving for a month and a half with the vacuum pump hooked directly to the wastegate actuator. Its far from ideal, but it gets me back and forth to work. I think it will make it another couple days.
Pulled it all apart again, did an even better job cleaning. relubed. exact same, reliable at 22in, needs tapped at 25-28in of vacuum. I ordered a new one, should be here in a couple days.
I decided to try my hand at taking apart the solenoid. Its bad, so what did I have to lose? You pry back the 4 metal tables from the mounting bracket, and pull the bracket off. theres a 1/4" steel nub protruding from the back side. give it a yank, and all the internals come out quite easily. Its...
I have a bad feeling the answer is get a new solenoid. It doesnt work when installed on the truck. No switching of vacuum at all. Good vacuum pump, no vacuum to the waste gate actuator at idle. I replaced all the cracked plastic hoses, and all the normal troubleshooting steps, to discover the...
I did a couple passes with gmtdscan running today, and I want to see if the numbers make sense. They seem alright to me (although the air temp is bonkers high). The truck is a 95 3500 dually, automatic, 4.10s, F code engine. As far as mods, I have the wastegate held shut with full vacuum, minus...
