You guys are really a sensitive lot. I never claimed my tune was correct as this is why I posted in the first place so please stop making stuff up. I asked for help on a shortcut to tweaking idle. ...

I don't believe you have never successfully MAF tuned one of these.

Yup!

Hey guys,

I have a TBSS I'm working on with a Truck Norris cam, most other things are stock except for a converter. I'm having an issue with idle. It will idle fine in P/N, but in gear it hunts...

Hey guys,

I have not used HP Tuners for boost control on a 370Z in the past, but I'm curious if there are any internal capabilities to do so. I believe ECUTEK repurposes the EVAP solenoid control...

Would you recommend scaling the whole table up so that the max RPM limit reflects the goal, or only scale the high pedal position cells and blend a bit into the rest?

As I understood it, which may not be correct, the "Shift Map" tables are for non-WOT pedal positions however I see that position 14 is considered 100% throttle. I'm just curious why it wouldn't go...

Hey folks,

I have a 2017 Mustang GT with automatic transmission that I'm really struggling with trying to raise the rev limiter. I have what I thought was all of the transmission limiters and...

Hey all. I'm not a super savvy Gen-5 tuner by any means. I ran into a small issue with a 2020 Camaro I need some help with. I feel like I'm making changes that aren't helpful.

This car runs and...

According to your log, it's only making 5psi of boost max and rolls down to about 1.5psi at the top of the run.

Unsolicited feedback -

I had Mike tune a problematic C7Z that I was struggling with for a long time. I was throwing parts at it trying to chase problems that Mike was able to sort out very...

Hey all,

Kind of a strange one here. I have a log from a 2018 ZL1 with a bunch of upgrades. It has the A10 transmission. Car runs perfectly fine in touring mode, but as soon as you shift to...

This setup doesn't have any EVAP system on it and no plumbing accomodations for it.

Here's an update. I smoked the intake and there are no leaks. I even swapped ECU's just to try something new. I've attached the tune file. More interestingly though, I have 3 log files attached. ...

Injectors are Fuel Injector Connection 1600's. Greg Banish does the injector calibration for them so I have fairly high confidence the data provided is accurate.

Thanks everyone for the...

Thanks for the response. This setup is running about 12 pounds currently. It's running SD for a couple reasons - less complication of MAF placement and frequency restriction with planned higher...

Hey folks,

I have a swapped setup here with a 5.7L engine and supercharger on it. It's running a SD tune. The problem I'm having is very inconsistent fueling between tuning sessions. One day I...

I think my low side fuel pressure sensor is dying. It often flat lines at 57PSI, but you can see in the logs it will periodically spike or read something different. When it's reading, it's around...

I made some fueling changes to commanded rail pressure and leaned it out a bit. I'm seeing mid-6ms injector times which I understand aren't great, but at least not way over the top. I have two...

I bought this one from Texas Speed, and I thought it was drop shipped from LPE, but I could be mistaken.

I took a second look at the commanded pressures and it doesn't command the full 2175psi...

Think I'd be better off going back to the stock LT4 pump? This pump is about a year old so I'm not sure when they went from V1 to V2 of the pumps, but a lot of these issues started once I swapped it...

Lingenfelter says their HPFP is LT1 based and recommends no higher than 2175psi, and states that their pressure relief valve bursts at 2755psi. That's why the rail pressure is significantly lower...

I see it's running pretty rich during the run. Let me lean it out and see how far I can pull the injector pulsewidth down. Looking at some prior runs with stock injectors, stock HPFP, same cam, and...

Thanks Alvin. Just a couple questions -

1. What are you seeing that gives you the indicator it's breaking up on the passenger side? Long term trims or something else?
2. I haven't tried...

I've attached another log from an earlier run. Here the manifold temps are definitely not as hot. The blower was put back on just a few hours ahead of these pulls so there was likely some air...
