Re: Inconsistent Injector Pulses in test mode

No, they are in parallel. This car was able to drive once. I think it would had never worked if they had been in series.

Re: Inconsistent Injector Pulses in test mode

Thanks for your replies guys.

These are Hi-Z Injectors. I tested each of them. They are around 15ohms each. The problem is happening in both banks. The impression I get is as if there wasn't enough current to move the injectors. Yesterday I added an extra ground to the MS. I also did the test ...

Inconsistent Injector Pulses in test mode

Hello

I have a 3.51 board with MS2. 2.92 firmware. It's installed in a 1986 camaro with TPI. It has 8 24lb/h SVO injectors in two banks.

I was able to drive this car once, just to a gas station about 5 blocks from my house. When I was returning from the gas station the car started acting up ...

Re: Twice Injector pulses during cranking?

I want to thank everyone who has taken the time to reply to my posts at any point in time. My engine finally fired up today!!

For anyone having the same issues as me, I'd like to leave for posterity how I solved my starting problem.

The problem was in the reqFuel parameter. I had lowered it a ...

Twice Injector pulses during cranking?

I'm trying to start my Camaro for the 100th time. I have a MS2 with board 3.0. Bought it assembled from a friend who gave up on his project. He bought it assembled from DIYAutoTune.

I'm currently on the Stimulator V 2.21. If I start with the RPM pot all the way down and slowly start turning it, as ...

Re: Idle PWM at 16ms?

Trakkies

No, I'm not trying to drive my injectors with a wall wart. I'm using a Megastim to test my MS II before fouling another set of spark plugs. The generic wall wart I bought for the Megastim has a voltage selector, but at 12V it only outputs 7V.

My problem is I'm getting way too high PWMs ...

Re: Idle PWM at 16ms?

Thanks for your quick reply Lance.

I still think I must have a parameter wrong somewhere. Even with your corrected voltage, 14.310 is still extremely high for my application. That's about what I was getting when I fouled my spark plugs. Even with the 6.55ms you mention I'll still be too rich. If ...

Re: Idle PWM at 16ms?

OK here's the datalog and a new msq file. Sorry it took so long. I can only work on this car a few weekends per year.

I decided to start over. Here's what I did:

-Flashed the latest firmware to my Megasquirt 2.920
-Created a new project and made sure it's using the freshly downloaded .ini file ...

Re: Fuel Pump Relay Behavior

Thanks for your replies.

Sorry I forgot to mention it's a v3.0 MB.

I'll replace those transistors and see if it works. However, I'm thinking about leaving the fuel pump relay connected to the ignition switch instead, since another transistor failure could leave me stranded in the middle of ...

Fuel Pump Relay Behavior

I have a MS2 with 2.90 firmware. Bought it assembled from DIYAutoTune a few years ago.

I had to connect the fuel pump relay to the car's ignition switch in order to start testing it because I never got it to turn on from the MS controller. I thought it was me who had wired it incorrectly.

Now I'm ...

Re: Bad module or false triggering?

Well my problems continue. The old module is acting up again. So I'm converting my MS to VR sensor so I can use my ignition box instead of the problematic modules. I'm outside US, so shipping a new module would take about a week.

I understand how to convert to VR and how to hook up the ignition ...

Unfortunately, more than 3 months later, I'm still having the same issue. Haven't been able to start my Camaro. I already changed the ignition module. Couldn't find a GM module locally, so got an aftermarket one. I also changed the VR sensor in the ...

It's a TPI engine with 8 high-impedance 24# injectors. Sorry I didn't specify that.

Do you think I might have the same issues as you?

I just finished my first Megasquirt install. It's a MS-II with 3.0 board bought assembled from DIYAutoTune. It's on a 1986 Iroc with a Chevy 350 engine controlling both fuel and a HEI distributor with a 7 module pin. The distributor has an Accel coil, if that ...
