that post didn't make 100% sense to me. I have noticed that with all the DIP switches OFF the unit is suppose to default to 100% but My results are completely different with them all swithed off...

Here is a warm start with the MAF unplugged. (IAT gets plugged in towards the end) my WB02 agrees with the mv on the narrow band

Tim @ ZZP says a turbo 3800 should idle @ about 1lb per min and...

I here is where I'm at, does anyone think is a vacuum leak think it's a vacuum leak?

Thanks for your input. at this point I'm thinking i must have a vacuum/boost leak

if I use a stock LQ4 maf table (multiplied by 1.78 for the AFC @ 82%) the cars Idles dead lean.

I can either...

That Actually changed quite a bit. I actualy got the car to idle nice @ 14.6afr. it did stall as soon as i touched the gas but it's a step in the right direction. I was just throwing big changed...

Huh... I forgot about that I have the IAT wired to a switch inside so I can pull timing for a anti lag effect. I'll double check the table and even try hooking the IAT harness back up to the sensor

I am a fast learner but I didn't expect to pick it up this slowly, I just don't know if it's me or if I have a mechanical issue.

About the Car:
It's a 1986 Pontiac Fiero that started out with...

For what it was worth, the issue was a stuck PCV valve.

Nope stock cam,

Will do, thanks for your time

I was just grabbing at straws before I tore it all back apart, I'm sure I have a vacuum leak somewhere the carb cleaner can't get. It does have a "miss" at idle and while trying to "power though...

I had the same issue, It seams like even after you update the driver, a restart is required just like the old days of windows 3.1, there is just no prompt to ask you to do so.

Also, while It's possibly the worst tuning practice EVER I got pissed and just mashed the gas at 30MPH the car droped to 1st gear shot up to 20PSI and the AFR when straight to 11.8 on the gauge then...

that's the thing in open loop the trims are sitting on Zero and the car is running like a lawn mower with the choke on. the plugs are black and nearly fouled. I replaced the O2 sensor & MAP sensor...

Sounds like a vacuum leak, but I have 19in of vacuum and i unloaded an entire can of carb cleaner all over the intake manifold and vacuum hoses with no result. and when I disable closed loop it's...

I have a Inovate LC-1 and gauge. I thought that a + fuel trim was adding to the desired AFR which would be taking fuel away. either way when I start the car my WBo2 says 7.4 (the lowest it will...

Hello, I'm not sure if I have a mechanical issue like a vacuum leak or exhaust leak, if I have a problem in my tune or if my injectors are just plain flat to big. My problem is a VERY rich idle.
...

Thanks for the tip, I was trying to figure out how to bypass the still functional IAT sensor. But what you say makes sense. If I understand you correctly you just use a resistor in place of the...

Hello I'd like to use a momentary switch in conjunction with the IAT Spark table to retard the timing as needed? How would I set this up? can I just set a momentary switch that interrupts the IAT...

I did, they are helping now i just sent them my SN

I was forced to do a system restore on my windows 7 PC and now I can't log in to the HP Tuners customer login. I can't reset my password because I have to many email addresses. am I totally screwed?...

That Fixed it 100%

I searched for "VCM Scanner.cfg" on my PC, found 1 result, right clicked and deleted it. when I opened the VCM SCANNER, it asked me if I was using Metric or imperal. and all is...

I was going to buy a mini for HPT, but when shopping around I found the ACER 5532 at best buy for under $300 and it has been a great. Just a thought. the battery life sux but it has a full size...

anybody else have this probelm? I have uninstalled and reinstalled twice now and downloaded a new 2.22.MSi off the Hp Tuners customer center. I miss my gauges :(

I have included a pic of my open...
