Driving home today I punched it and lost all my boost. I have the R9 and have had almost no problems. could this be chip related?? what would cause no boost??

Thanks all

I just put my r9 in a couple of days ago and it did the same thing. Mine would lose the boost as soon as the 1-2 shift occured. I did some searching here on this board and found where some guys were unhooking the wires going to the boost control solenoid. I unhooked mine and it hasn't lost boost since (driven about 100mi). I e-mailed Mike Troyer about this and he is going to do some further checking to see if this is a widespread prob.

You can disconnect the plug for the dump gate. So that the ECU can not open the dump gate. We have figured this out from haveing this happen to use alot. Jerry Green (SVE engineer) also told us that this would fix this little problem. The plug is kinda hard to find, so i will take a picture of the sensor soon and show you where it is. It is also affected by heat, so down here in Texas we disconnect the sensor for the track and re-connect it when we leave.

 

Two things usually cause it, hitting the rev limiter and hot transmission(burnouts). The 1-2 shift is usually the rev limiter bump.

Very good questions! I was on the PSP Board and found that very fix. Mine would lose boost occasionally on the 1-2 shift. However, it was never consistent. One time it would, the next time it wouldn't.
I unplugged this sensor, located on driver's side of supercharger with vacuum lines attached to it. No loss of boost anymore and as a bonus I got another 1/2 pound of boost!!
Definitely a low-tech mod that works! No check engine lights!
I called Mike Troyer and he said I was the only one to report a problem like this. He noted my history and asked me to keep him informed.
Note: Mike suggested that it could very well be the transmission either fluid changes (too hot and causes it to go into limp-home mode, and has other inconsistencies). Mike suggested a shift kit and synthetic fluid.
He said that unplugging the sensor will also solve the problem but shouldn't be necessary.
I've decided to leave my sensor unhooked for now.
Hope this is helpful!

I had the problem at the track with 1-2 upshift (tire spin) and lost boost down the track. I had a 14.8 but still won by .008 second on the 1/4. But if this is a problem then Superchip should reprogram the R9 chip to fix this over rev-limit Boost kill. We shouldn't not have remove any connectors to still have Ligntning with Boost! My .02 worth.

Rev limiter is set too close to shift points. Mine is set at 6500 well away from 5500 shift point. Watch rpm when doing burnouts. I never let mine go over 4000. I am the only one in are group to never have lost boost. Mike can set the rev limiter up he just doesn't like to but it needs to be well away from your shift point because the shift point can vary. I don't know why but it does.

mine has loses boost every time when it is still running cool. when i race at the track i have to go right in the lanes soon as i get there. with the jl chip it does not do that. i had the old rpm file. how many rpms were you turning at the 1-2 shift, mine was turning around 5700 rpms, that was too much. IMO it needs to turn around 5400 or max at 5500.

Ryan2KRedL: He's yanking your chain, nearly everybody had loss of boost when they first came out with the chips. Kind of embarrassiing to make a 16 second run with a helmet on.

4D Thnder - I was skeptical also on that comment. But other than that I'm real happy with the R9 and unplugging the sensor has solved the problem. Now I'm torn between buying a NOS kit, throttle body, intake and some kind of exhaust work or just buying my chrome L wheels and snugtop......decisions, decisions!!!
To compound the problem I'm getting married next weekend!! Talk about cash flow problems!! LOL!

Hi Guys,

I saw this thread and wanted to repond publicly to you all.

We currently have hundreds of Lightnings across the country, both 1999 & 2000 models, running the R9 program. To date we have about 8-10 or so reports back to us here at Performance of loosing boost during the 1-2 WOT upshift.

What happens is the ECU sends a signal to the wastegate solenoid to instantly dump boost when the engine hits 5650 rpm during the upshfit. This is a protection mode that we do not attempt to defeat.

We have set the WOT upshift point at 5400 rpm in the R9 programs, but as usual with these Lightings, there are always a few that are somewhat inconsistent as to when they actually *execute* the upshift under certain conditions, like spinning the tires going into second, or after a hard burnout, or just out of the blue, etc. There can be any number of reasons for this, like a too-small orifice size in the PCS (pressure control solenoid) of the transmission not allowing enough fluid volume to flow quickly enough, we've seen this on a couple other late-model Ford automatics like the 4R70W's and even some of the front-drive Taurus automatics. We've also seen when tranny fluid gets very hot, that shift characteristics can vary a bit, which is why we suggest making sure you've got a high-quality aftermarket synthetic fluid in the tranny.

One thing that is very interesting in the reports we have had to date is that this is not consistent even on those few trucks this is happening to. Sometimes it happens, sometimes it doesn't, showing clearly that it's not a simple thing like the WOT upshfit point being too high in the program itself. We have not had one person tell us that this happens "all the time", on *every* WOT 1-2 upshift, regardless of whether it's from a full-throttle downshift into first, (a rolling start) or taking of from a dead stop and doing WOT runs.

In the last programs for the Lightnings, we had the WOT upshift point set at 5550 rpm, 100 rpm below the boost-dump mode, so it wouldn't hit it, but a few still did. So in R9, we deliberately set it lower, down to 5400 rpm that was used in the very first Superchip Lightning programs, and we see that there are a few trucks that are still occasionally hitting the boost dump mode.

We have of course let the engineer who is in charge of Lightning program development know about this, and they are going to take a good look at this to see what can be changed to help this. Of course the WOT upshift point can be lowered still, but since this is not a *consistent* problem, that doesn't seem to make much sense since we're already only 150 rpm above the factory WOT upshift point of 5250 rpm (a figure you can use to check the accuracy of your factory tachs, by the way). So they'll be looking at this, and we'll let everyone know what they find, what they suggest, etc. For the short-term, as many of you already know, disconnecting the wire connection to the wastegate solenoid will of course defeat this protection mode. I personally would like to ideally see a long-term "fix" for this, but that is most likely going to vary a bit based on each vehicle's characteristics.

One thing that would be very nice is if we could get our hands on a Lightning that is exhibiting this delayed upshift, to try a number of different things to see if we can effect a "fix" for these inconsistent delayed WOT upshfits. If there is anyone who lives in, or who can get to, the Orlando Florida area where Superchips has their US development facility, please let me know by contacting us via email or phone, our contact info is below, and we can get a session set up for you.

Our bests to all,

I have a shift kit and before adding the chip was hitting the rev limiter, causing loss of boost. After I added a chip, I STILL had this problem, so I disconnected the battery to clear any codes from before. It seemed to work great, but I STILL lost boost, however it was only occasionaly (very inconsistent). I think the best solution for consistency is to disconnect the sensor, at least when you are at the track and plan to do burnouts, etc.
