Well, it wont start on stock. With the supercharger system and everything installed, running stock is not an option. I think something may have happened to the VSA module. I'm going to check the fuse and i'm hoping it's that.

Can you confirm that the VSA codes would cause the no start issue?

We got it started again just now.

Same process. We cleared the chassis codes that were in there. I reflashed to stock, and then to my map and it started.

Problem is, it's done this twice now....it will run like this for a day and then sit for long enough and not start. Only thing that works is ...

Battery ground and power

Sorry, here is the pic.

The battery went dead twice trying to start it due to the sheer number of times i had reflashed to stock then my modified map. Both times it has taken a charge well. The battery is less than a year old.

So should i be looking at my grounds then? I did have the ecu ground on the fuel rail, but ...

I'm charging the battery now, i will do the "send support information to hondata" as soon as it's back. Do i need to be connected to the internet as well to do this?

The green check turning to a red "x" occurs only when the key is in the start position.

Also, i took the car back to my mechanic ...

So another update. Here is all the relevent information regarding the problem as it sits today.

FP Serial: FP-SI-16339
FP Manager Ver: V2.3.6
Datalog: FP records nothing of no-start
Car: 2011 Civic Si (north america)
ECU type: OEM Honda ecu
Mods: Kraftwerks Kit, Hondata 4 Bar Map, NGK 2669 plugs ...

So when i go to datalog the no start, the green check box for "ecu" and "live" turn to a red "x" as i am holding the key in the start position. Engine just sits there and cranks.

I looked at the datalog, but it doesn't seem to really have recorded anything? I see the throttle plate value fluctuate ...

I'll do a datalog of the no start here in a minute and send it to him also.

I just sent him an email earlier today bringing him up to speed, just waiting to hear back. He was aware of the issue, but we thought i had it solved after i had gotten it running this last time. On the datalog i did when it was running, he said everything looked great.

Of interest....my mechanic also said his scan tool had issues connecting with the ecu. But when i hook up the laptop and flashpro, the program has green checks next to everything and is telling me the ecu is in normal mode.

I am using software version 2.3.6.0

The calibration type is a custom map from Vit. It's a basic starting map, and the car has run on it. It doesn't say anything about race or normal in the information for it that i can see.

I've gotten the car started normally on two occassions so far. Both times ...

I just installed a Kraftwerks Supercharger kit in my Civic SI. When I reflashed the car with a starting map I got from VitViper, it would not start. I read the post he had made about this being a common issue and being caused by the software not detecting the ECU.

So I plugged my laptop into the ...

So my car was involved in an accident, and I'm fairly certain insurance is going to total it out. I tried flashing the ECU back to stock, but everytime I try to unlock the flashpro, it tells me I need to upload a stock calibration first. Is there anyone who has experienced this problem before and ...
