Got the truck to a good solid state of tune finally. I managed to get my headers to quit leaking, cleaned my injectors in my heated ultrasonic cleaner while pulsing them with a varying square wave of...

I have a minor update on my progress with the truck. I've spent some time getting my truck hooked up to my laptop and familiarizing myself with MPScan. If i use SBEC t1 for my port setting, It will...

I found a couple threads that jwillis84 had some input on. recent ones too. I've seen all of his youtube videos on the DRBII and some of his stuff on other forums. I'm excited that someone else...

Got my DRB-II today. I love it. Found that i have a really lazy o2 sensor, ordered a new NTK one.

I'd be interested in it. Like vprtech stated, jeep guys and truck guys would be down with the idea. Had a 94 4.0 jeep, wanted some tuning and logging support for it, now i have a 318 truck with a 90...

UPDATE: I ordered a DRB-II with chrysler cables and a Super Cartridge V8.0 on eBay. Scheduled to be here this week. I know i can get detailed live data with it and run tests on solenoids and stepper...

Does anyone have any Cal files for the SBEC TBI 318?

open-loop idle you say? explains a couple things i noticed it doing before the o2 sensor was installed.

EDIT: the truck runs like it has a totally different engine in it. Its impressive for stock...

That makes a lot of sense. Kind of like how a lot of cars that were super cheap back in the day were actually really good quality but since they were so cheap, everyone said they were disposable and...

I just was talking to a friend today about doing a TBI 318 swap in his '72 duster. Then we got the brilliant idea of doing just what you said, TBI on the slant-6 that's in it since we love that...

I have the truck running on the TBI setup now. Starts easy, has good throttle response, and idles well. Seems to run rich. That's probably because its in open loop due to the fact that i don't have...

Update on the truck. I've kind of gone backwards with installing all my parts from the '90. I've installed the A/C since its been getting toasty in GA, and now i have my new doors on and power...

Hey everyone. Its been a while. I have been busy changing jobs and the week after i posted this thread, the original engine in the ol dodge spun #6 rod bearing and flattened a few lobes. It...

Hey guys, it's been a while. I recently traded for an 87 dodge d150 with a 318. My first actual dodge. (Jeep was my first chrysler vehicle) At the moment it has the original Holley 2280 2 barrel and...

On a 93 T3, its the first line. What is labeled "AccPumpScaleDeltaTPSFromCoolantTemp" is what determines the pulse width that the computer uses in this instance. And i also know that the computer...

ok. it actually looks quite similar to the one on my jeep and its c101 on both of them. i'll see what i can dig up there.

Actually, i think yours is also referred to as a C101 based on the list of connectors i have on my screen. I'll do some more digging. I have the same picture of the two connectors posted above, so i...

It is quite tedious. I am really excited to see what others will be able to do once the door to the 4.0 is open. They have a lot of untapped potential, even in N/A form. I thought it was pitiful to...

i have alldata. do you have any idea what the number is on those connectors? e.g. early 4.0 jeep bulkhead connectors were called "c101" by chrysler.

Well, just to say i loaded a jeep cal into mptune, i borrowed (kinda cheated) a .mpt file to see if there was any parameters that matched up between for instance, a tIII and my jeep. i can tell which...

Would something like this work as-is with MPScan? http://www.ebay.com/itm/USB-2-0-DB9-RS232-Serial-Converter-Adapter-DB-9-FTDI-Cable-5-Feet-ft-NEW-/111139070965#vi-content

I've added some more stuff to my symbols file, now i'm trying to figure out how to make it into a table file so i can use it in mptune. and does it require me to add it to something under the master...

I had a wrench thrown into my gears last Thursday. The PCM has failed. Sounds crazy? Well i tested it using the TC-2A diagnostic flowchart that i got from the FSM. I was coasting down a hill and lost...

i understand that. the on/off telling the pcm what revolution the crank is on. like 1-5-3 or 6-2-4. or 1-3 or 4-2 on the datsun engine. but it still may be a task to get it to actually function...

I feel like by the time i'm done with this whole deal, i'll be so familiarized with the obd-1 jeep system that i may build a custom intake manifold for my Datsun's EFI setup and just using the...
