Want OBDII!!

[Injected1]

Ok guys I haven't posted in a while due to my unfortunate loss of yet another Sy motor. I can't figure out this OBDI and no one would help me learn about it. So after the last motor went I tried to sell everything and do and lq4 but ....no dice. So the built block I offered up a while back is now going in but I really want to run OBDII without spending $3000 in a standalone unit. So my question is- What is the easiest and least expensive to convert my vortec head 4.3,T74, 700R4 (RPM) to and OBDII setup. I can't afford to blow another motor so I need to deal with something I know instead of something I want to know.

PLEASE HELP.....I need to know what I need to buy. I only have 1 month to do the build before I lose my shop I work in.


Thanks

Re: Want OBDII!!

Have you checked out the Code59 forum?? Seems to be working great for a number of guys... me included

Re: Want OBDII!!

I am confused. You feel like you didn't get enough help/info before with the stock computer, so your planning to make a change that i don't think I have seen ANYBODY in syty world do in hopes to have more help/info?

Re: Want OBDII!!

I'd think you'd need to run a newer 4.3 OBDII setup. HPtuners and EFI Live will support I believe the 98-up 4.3's, but then you'd need to purchase all new tuning software and probably transfer your build to a newer block to accomodate the crank/cam sensors and stuff.

OBDII isn't all it's crack up to be either. It has it's advantages, but with FI more and more people are simplifying things. Converting to custom OS and running speed density in order to ditch the MAF (much like these trucks are already). You basically just tune off of the VE table, which is the F29x table in code59. The PE table is set to 1.00, as is the boost enrich table. Hell people are running open loop all the time too.

OBDII does have the advantage of controlling a transmission though, if you want to run an 80E. If you can't grasp OBDI tuning, then ODBII with its vast array of tables might be even more intimidating. Especially the Gen IV V8 stuff!

I would look into Megasquirt if you're on a budget, don't want to mess with factory stuff and want a bare bones yet effective EFI setup.

Re: Want OBDII!!

what information are you looking for to help you tune. there asre a couple excellent sticky write ups and several bins to get you started.

Re: Want OBDII!!

I would just bite the bullet and go to a known good and proven tuned and ask them what stand alone they could work with your build on and pop that sum bitch in and have them tune it for you since the self tune with obd1 isn't working out for you

Re: Want OBDII!!

Hate to rain on your parade, but there is *no* PCM/ECM/Aftermarket ECU that will tune itself and fix your detonation problems for you. You'll either have to take the time to learn the process (which will take a fair amount of time), or pay someone to do it, which will involve money.

It always strikes me as odd, that people are willing to spend big $$ to rebuild motor after motor, but are unwilling to load up their truck and bring it to a qualified tuner. They'll drop $400 on a BOV or a boost controller, but balk at paying a tuner that.

but you can sit around and fondle the bov while your truck isn't running while fondlin your tuner probably isn't an accepted practice

That something I don't understand either. I see people spending 5-10K on an engine buildup just to skimp on buying a wideband. On the HPtuners forum there are always people coming in with H/C Gen III/IV's that want to tune WOT off the stock O2's. WFT?

Learn it yourself or pay/fondle a tuner.

For some tuners that's as good as money.....:rotf:

Not me, BTW. :tdown:

That's the best two paragraphs ever stated. Take it to hart. I've seen more Sy/Ty and especially GN guys put $hit loads of money into their stuff only to run piss poor times and or blow it up. Why? Their stuff isn't tuned or matched. or worse both.
I don't mind Code 59.. it's very very nice for a stock ECM setup. Very tuneable.
I went with XFI this year for many reasons... (Jeff calls me a traider now) but XFI has alot of advantages over a stock Ty ecm.
Do some reading... ask some one... Use some comon sense and start out slow if you've got no clue.
Read some more. And then some.
Forced Induction is not a microwave dinner. It's a slow cooker when it comes to tuning.

Well thanks guys but there are mitigating factors that some of you might not understand.
1. I have spent the money on this motor over a period of 2 years and done it all myself.
2. There are absolutely no syty'ers anywhere around me that know about tuning (at least that I have found).
3. I wouldn't mind paying someone to tune the truck but I want to learn it also and i do much better watching someone.
4 The only person I know of is Mike hood in Savannah, GA and that is almost 8hrs away.
Does anyone know someone they trust 2-3hrs away from Destin,FL.I want this done so bad that I would even put up a couple people for the weekend/week in my house 2min from the most beautiful beaches in the world. Anytakers let me know and I will contact you when the motor is in.

Thanks, Nick

buy Hood a plane ticket, house, feed, and pay him and your done...

Re: Want OBDII!!

Get an Ostrich and talk with some of the aspiring FL tuners (Ian, Tyson, etc...). One of them might be able to help you out on short notice. Is your build off-the-wall odd? If not, have you tried any of the tried-&-true code59 bins out there? I'd be more than happy to help you learn to tune on your own if you feel like tackling the endeavor.

Just LMK.

Re: Want OBDII!!

Nolan (10secTy) has been tuning trucks over email for years, hit him up, he's one of the top syty tuners! and he does like to be fondled

I have no tuning software as of yet but will purchase it for this build

What do you think?

 

[JSM]

Re: Want OBDII!!

So you have 75 lb injectors and a 50lb chip?

Did you do any driver upgrades to ecm to run the 75's?

All the money in parts and your expecting an off the shelf chip to work? Esp one not even programmed even close for your combo?

 

[Injected1]

Re: Want OBDII!!

I know that - I wasn't ever planning on using that chip - I was just mentioning that I have it if anyone knows someone who can reprogram the drivers to my set up... Or see if anyone has a better option to suggest.

 

[JSM]

Re: Want OBDII!!

Drivers are not "reprogrammed" when you go to 75# and larger injectors there are physical electronic components inside the ECM that must be changed out. Solder is involed not a laptop.

If you go to 60/65's that issue is avoided.

You will need a custom tune for things to be RIGHT. That will involve someone (yourself or a hired tuner) to actually look at the logs from your truck and make corrections. These will probably involve I would guess 20 or more trying of different chips in order to get you close. Basically it will take some time.

I could send you some 75# programs, you can login to code59 and download them for free. They would be a "start" but if the truck were mine I would spend 20 minutes on idle before I even left the driveway and probably made 100 changes before leaving the driveway.
