What are the plugs and gap?

Maf period is = to 1,000,000/Maf Hz. So 12.5k Hz equals a Maf period of 80. 5,000 HZ would equal a Maf period of 200.

The only system not messed with is the only one that won't set lol

I am messing with an ecoboost I've done a similar tune for. My problem is that I can't get it to complete the "fuel system" to save my life. I've tried following Fords trip to ready that monitor with...

The car is commanding .60 to get it to idle at 1.0. If the car was running correctly and is now this far off without increasing the MAF tube size by about 2", this car has vacuum leaks, or major...

Low vacuum at idle is also another sign of a leak.

Fuel trims are adding as much as possible to try and achieve stoich. It's commanding .61 Lambda to try and bring actual lambda to 1.0. Either huge vacuum leak or MAF cal is way off. Check injector...

A lot of the T4 housing small turbo kits have very bad valve float issues with the stock cams, not to mention with larger cam profiles.

I'm not worried about the transfer. My car is +-2% fuel trims with stock and lu47s. I just installed dw95s with their injector data and +20% fuel trims at idle. Cleans up by 3-4ms but off bank to...

Do you have a very accurate maf transfer for that whipple? I'm curious to know the fuel trim change by just switching in those injectors and values.

i would put a mechanical gauge on it. Make sure the pump booster is upping voltage before the fuel solenoid opens.

What fuel? Sounds like it's dropping fuel pressure on the initial hit, then struggling to catch back up. I would put a mechanical gauge on it. When you put the larger fuel jet in, it could have made...

The intake track behind the MAF is under a vacuum compared to outside air. Unmetered air is being sucked in behind the MAF. An exhaust leak or bad o2 could cause it too.

You need to scale the MAF period. Kind of like I did here. You may need to go a little more, This car was only seeing 6-7psi68734

Post a log. Did spark end up around 18*?

Awesome man! Also, I usually set the fuel base cold high load to WOT AFR, and Fuel Override to WOT AFR just in case.

I may have had that backwards on voltage then. I forget. There is a reason it's staying closed. I'll be back to my computer in a few min and I'll take a look at the tune/log. There are a few things...

Murphie, you can log manifold control runner voltage. I think 3.92 is what is typically closed IMRC, 1.17 or something is open.

Data log VCT intake and exhaust cam angle. If it's not hitting OP VCT timing, the intake cam will be around 0* and be down 200whp. 10psi and e85 on the last S550 TT I did was 832whp, 710wtq. MAF...

What fuel? Here in Cali on 91oct, it liked around 24*. Used GT350 Tbody data and plenum vol. Has a PMAS CAI, but everything else is 100% stock. Played with IMRC load for open and close a little to...

Awesome to hear. My customer is an auto car so I am hoping I don't run into too many surging issues. He is dropping it off late today, so Monday I will report back with any discoveries. Did you blend...

What was your surge issue you think? The last Procharged car I did, taking a little bit of spark out of where the car was transitioning to boost around 3k really helped a lot.

I'll be doing one this weekend. PMAS CAI though.

Ah. Skimmed through and didn't realize he didn't have a 15+
