Logs and Issues

[bushido_70]

Hello,

First time contributor to this site, but i've been reading up for quite some time to help plan my upgrades on the G70.

Current set of mods:
Ark performance catback
Agency Power Intercooler upgrade
AEM CAI
Velossa Snorkles

Gas:
91 octane with 16oz. Royal Purple octane booster

Elevation:
5,403ft. (Aurora, CO)

I just got the JB4 installed, with fuel wires and Denso plugs set to .022. Had a few runs on the dyno on map 1, 2 and 3 (logs attached).

First, i'd like to have someone knowledgable take a look to see if the readings in the logs are ok. The shop that installed the JB4 stated that Map 3 seem to have the smoothest AFR readings and best performance.

Second, after parking the car for a while and driving again ( a few hours after getting the JB4 installed and doing runs on the dyno), I'm noticing that the car won't speed up if i step on the gas. I'm not seeing any check engine lights, or error warnings. Car seems to drive fine up until you attempt to send it. Not sure what the issue may be, but I figure i'd ask here to see if anyone would know what could be the cause.


Thanks!!

Did this ever sort out? I took a stab at your Map 3 log. I'm no expert but I'm trying to get better at reading these. 1st, your boost looks a little low. Map 3 you should see higher than 17 pounds, especially at that elevation if my math is correct. You should see closer to 19. If I was a betting man it's because of your fuel. 91 with just a bit of octane boost probably doesn't cut it. You need 93 with E85 mix if you want to safely run Map 3.

Check to see what map the jb4 says you’re in. Sometimes if it over boosts jb4 will put you in map 0 limp mode.

JB4 firmare is really old so update that to v19, and then do a few more runs. Make sure app is updated also and set app to conbine logs into one file.
