WILL IT START? Holley Terminator X Troubleshooting on a Spicy 6.0 LS Engine Swapped S10

[@SPPTVarmy]

This time on SPPTV Rob and Mike go to the rescue to prevent our friend Jerry from selling his brand new Terminator X! Will it start? Everyone has been through, or knows someone who has been through their first standalone EFI experience. Some with HP Tuners, some with Megasquirt, and many with Holley EFI. The Terminator X is sold as a plug and play solution for people looking to run an LS engine in a project vehicle. In most cases it probably is, but that depends on everything being correct mechanically with your engine; and all the information you plug into the Holley Terminator X ECU. If the computer does not know what specific parts it has at it's command, it will not be able to work as it should. We realize drilling a hole is not optimal. But the IAC settings seemed to effect no change, and we were trying to prevent a carb from being put on this sick engine! Plus the TB with the hole won't be on the truck much longer, and will be replaced by a larger unit and TBSS intake. This was just an exercise in making it run for now. Jerry's truck has been around for awhile but this combination is all new. it is a 6.0 based LS with aftermarket heads, a cam with over 240 duration, and nice parts throughout. If this video reaches 500 likes we will do a closer look at the truck once it is cruising the streets!

Hey guys just FYI most LS Holly setups you have to crank open the throttle body including the stock ones. Then you do TPS resets. When you can adjust it to where the IAC percentage is between 5 and 10%, it's almost perfect every time.

[@darrenlooper1095]

Yeah definitely need to do a tps auto set in the wizard after adjusting the throttle adjustment screw

[@SPPTVarmy]

We did

[@brentspence3379]

@@SPPTVarmy there's also iac parked which you may know cranking air and iac hold position which is basically like base idle airflow in hp tuners

[@darrenlooper1095]

@@SPPTVarmy awesome, yeah the terminator is badass for sure . They just have weird little quirks to get used to but once you do they are pretty dang sick

[@MrAllan5oh]

Good job guys! A few tips. "Startup IAC position - hold time" set to 0 so idle spark and IAC control takes over immediately after initial fire. The learn table is always active, you don't need to transfer learn to base for it to change fueling. Always say no to smoothing and smooth manually. Always need to do the static timing check after first fire. Idle spark control will do a max 8 degrees + or - from your base spark table. Usually you have to jack up the "IAC parked" table with a stock style TB on a cammed engine. I like using the strip chart for start and idle tuning. Aim for 2% or less IAC at warm idle at target idle RPM. Happy tuning.

[@HeadFlowInc]

He should have picked a tune from the tune files as a base tune. Simple then let it learn from there. Well crap that Camshaft must be huge with a really low manifold vacuum at idle. Good work guys that was a challenge!

[@BDauto86]

Yep exactly what I would do. I bet that aftermarket tb needs the IAC passages ported and the inlet before and after throttle blade opened up or like you said it's just an aggressive cam profile and tricky.

[@stevenayala2324]

thats bad ass yall went and saved the day so he can ride lol good looking out Rob and Mike

[@yahawashitheserpentofbrass2140]

You have to get that IAC count down to 2 to 10% at above 160 degrees. Tune the throttle screw up or down depending on IAC count then do an auto tps reset. U have to keep doing it until the IAC count is between 2-10%..

[@njracing4397]

I had a very similar issue with a turbo 6.0 . IAC always 100% and wouldn’t idle. I tried another IAC then another map sensor. I was going to try and drill TB because at 1500 rpm holding blades open it seemed fine. I went back through the wizard and realized I used cam duration at 007 lift since it was first duration number on cam card. When I switched to duration at 050 lift truck idles great and went right into learn mode.

So Rob and Mike are kinda like Batman and Robin in a Tuning emergency? To the Carb cave Batman.

[@robertironside3166]

Looks clean... very clean. Stock regulator a problem if it doesn't respond to the new kit? Good point... I have no idea.. can you tell? lol

[@michaeldavis1718]

Mike, please learn more about Holley. I love your guys videos and have a Holley Terminator X max myself and love to learn from you guys!!

[@brendenkesterson9200]

Sounds like the same issue i had check your sensors for .5 volts. My fuel pressure sensor was my problem. As soon as I unplugged it it fired right up and no longer had problems

[@bobg4654]

Before you commit to drilling it pull a vacuum line and see what it does with more air.

[@rpturbo]

Mike you did a good job with no Holley experience. As you seen, it's pretty easy to use. If you can use HPT, Holley is way, way easier, and not only more intuitive software wise, but controls better. If you transfer the learn to base, it is more accurate than transferring the difference in fueling in HPT.

[@jord9308]

Watch Joe Simpson’s vids- he has a tuning class for Holley starting soon

[@tommys2979]

Holley has a good 18 minute video about getting them going on ls motors

[@nicksimeone8933]

You have to do a TPS relearn every time you adjust the throttle body

[@jasonhastings5538]

Those things will drive you crazy!!!!

[@ritchardposterior262]

next time, install the set screw in the throttlebody lol. that way you can set idle till IAC is at 10% or less

@@BDauto86 the tuners i used locally claimed to be good with HP tuners but both never used holley before and both had my truck months claiming to be getting it dialed in with no success and kept my money claiming it as labor fees. I switched from my stock harness and ecu and went to the terminator x max for the self learning capabilities and not being a slave to tuners any longer but not knowing its really not that simple. My truck isnt even anything crazy, its a 99 gmc sierra slammed with a cammed 4.8/4l60e with a 3200 stahl, 48lb holley injectors, 102mm tb, sheet metal intake, headers and fuel cell with a inline pump

[@BDauto86]

@@brianmay8445 majority of my tuning is HPtuners as well, each platform is setup alil different but it's all similar strategy. Holley has a nice setup but ppl push that self learn and your correct it's not that simple. Even at that, it's still a base tune and needs correction. Sounds like a fairly common/basic setup, I hate to hear you've spent good money and havent got the results your looking for. I was just curious how far away you are cuz I'd be willing to look at it for you but that's pretty far off from central PA. Hopefully you get it dialed in and working well.

[@mcfero1]

Wow that sucks. My terminator is has been going great for 2 years now. First was stock now cam and springs. Next up is turbo. No professional tuning just watching joe Simpson videos on KZbin as well as sloppy mechanics has a good homey n/a tuning video out. I wouldn’t take my car to a tuner who has not used Holley.

[@1Kile1]

More power to you guys. As someone who tunes holley, this video is so cringe to me. You did well to troubleshoot though not knowing the software.

[@sticc2itgarage672]

Read the instructions did you DO TPS AUTOSET?

[@billwilliams2242]

So he has it set up speed density

[@nocturnalspecialties642]

On a stock throttle body, take the idle screw out and thread it in from the top. Gives you more range of adjustment and easier to adjust. Also start out with more airflow than you think you'll need. Its easier to work to down than up. That way you dont have to do a TPS autoset every time only till you're done.

[@jord9308]

The throttle needs to be cracked to just below desired rpm, then do tps reset - that way IAC doesn’t have to work as hard

[@SPPTVarmy]

That was the thing, we maxxed out the throttle adjustment screw, did a tps re learn, and it still wasn't enough, behaved the same basically. The Shithorse is DBC and works without a hole. But this S10 has big ass ported heads, 240+ duration cam. We could have just pulled the IAC and saw if it ran like that. Likely the 2 IAC's we tried are faulty. I found several guides on setting them up in the Holley software and none of the settings suggested made a change.

[@terrypickette118]

👍👍👍

Holley EFI has the ability to change the option for cam and tps relearn.. You guys should've watched some more videos lol get ya some more learning HOLLEY efi is far easier than HP tuners

[@Avalanche2]

99% of the initial start issues w/ term X are the MAP, even when it works nobody gets it right for some reason. I knew it before I even clicked on the video. Also, throw those chinese throttle bodies in the garbage, they are 100% junk and a waste of money. Not using the wizard base tunes is a mistake.
