Ok so today I reflashed the DIYPNP with GSlenders V2.8 Firmware, moving from the Release Firmware 3.2.4.

It ran fine on 3.2.4, drove 300-400 miles last week on it...Now it just about starts, but idles badly and stupidly rich (8-10 AFR), up in the 100 fuelload% cell. Unsurprisingly it stalls after not long.

Any ideas what may cause this? Any settings in the new firmware that I may have cocked up?

I did the firmware change, reloaded my MSQ from the previous firmware (which ran fine) and checked calibrations were still ok.

I'll chuck the MSQ online in a minute, would anyone would be kind enough to take a look? Or I could capture any specific menus if easier?

It's a DIYPNP with Sequential Injection added and 650c FIC injectors. Mk1 1.8, NA.

 

Just occurred to be I did have problems loading the firmware in the first place. I pulled the ECU to do the changes to A/C Routing. When I first tried to start it in the car again it didn't work at all and stopped connecting the laptop. Pulled it again and did a clean firmware install and it started the car fine.

I've been assuming it's a problem with the MS settings but could I have fried something?

Current MSQ, now in my dropbox folder: http://db.tt/5h4Pwld7

Previous MSQ (Working on 3.2.4): http://db.tt/KCJ51IXN

It's got me concerned, If I don't work it out tonight I think i'll pull ECU again and go back to 3.2.4. Need the car working again by Wednesday for Glastonbury!

 

did you forgot to plug in your MAP sensor?

 

Ohh ffs....shoot me now.

Thanks.
