This far everything looks great :thumbsup: (except valve covers, oil pan and oil filter which vere got some damage) It was last summer when i bought it, but it was $1225 including shipping in us (i had to pay more to get it shipped here, but it is different story) It has Non turbo hummer...

I Bought 6.5 humvee engine from fleabay and disassembled it yesterday, here is some pics what i found: http://kojo.wippiespace.com/images/album/506/

Maybe he hasn't noticed but everyone can read his VIN through windshield):h I understand if you want specificially heaths tune, but just fast reminder, there are other options like http://walkingjdesigns.myshopify.com/products/kojo-tuning-6-5-diesels

Yup, if you send both VIN's i can check if there is any major changes in programs.

2500 and 3500 has propably different programming for transmission, cant tell exactly without VIN codes. Computer doesn't know ratio in our trucks or tire size either, those must be programmed to VSSB factor, saying it other way computer want only x pulses/mile from vehicle speed sensor...

Looks really good.. i would order one, but i allready have FTB :D

Finnish Suburban drivers meeting will be this year at Koljonvirta camping, iisalmi, Finland. http://www.koljonvirta.fi/ reserve 24th-26th september from your calendars, and bring own beers ):h http://www.facebook.com/group.php?gid=129874717036347&ref=ts#!/event.php?eid=125621327475934&ref=ts

Away from them. cylinders are everytime filled full and fuel solenoid controls that spill valve so when computer wants start injection sycle it gives pulse to pmd which closes fuel solenoid which closes spill valve and when injection has been on enough long solenoid opens and spills rest of fuel...

That book is mostly fuel system, and most of that book is pump and ecm things. There aren't any torque specs, clearances etc for pump, but for example there is pretty well explained how fuel metering system works and things like that (by the way it is spill valve)

No i havent, i have noticed it really gives power at high rpm's, but i havent raised rev limiter. i think it would need at least balanced engine and maybe stiffer valve springs to take more rpm. I believe too heaths race truck uses rpm to make power. __________________

I think this book would be good for any of us if thinking mods to ds4.. http://cgi.ebay.com/ebaymotors/1994-GMC-Chevrolet-6-5-Diesel-Electronic-Fuel-Injection-_W0QQcmdZViewItemQQhashZitem5887b7b068QQitemZ380234084456QQptZMotorsQ5fManualsQ5fLiterature I have one of those (has been years) and it...

No, yoy dont want.. when solenoid is open pump doesnt deliver fuel. Injection happends as long as solenoid is closed...

If ANY questions comes to your mind you can always ask for help here, here is lot of knowledge about these engines..

There is some ash (from iceland) on my crystallball, but i see clearly it is allready shipped ):h

Could be failing app sensor..

If you want max MPG you should use your engine at max torque rpm's Programming makes that torque curve more wider, so torque isn't anymore just peak @ 1800-2000 I believe mpg gets better if you dont drive more aggressively then with stock program, i have noticed it by myself and many of my...

I dont personally know anyone who likes trans slamming gears in.. but my opinion is shift shouldnt be too slippery. I didn't any changes to shifting parameters in Dan's tune so only thing what can make it worse with tune is following two facts: -More power makes bigger slam -Computer calculates...

Dan i think greg is vendor here, so it is legal to publish link? http://lubricationspecialist.com/front/shop.aspx?catid=10&parentid=0&productid=74

I have measured 3 suburbans with chip and stock style liftpump. in everyone fuel pressure dropped below zero when accelarating at full throttle. Meter was connected to water drain valve so there is still some restrictions after that when fuel is going to ip, but ftb takes care of them, and...
