Hey guys,

I recently migrated to the AEM EMS and I have finished the partial throttle tuning. I am ready to tune for WOT but for some reason when I floor the car it's like hitting a brick wall. The car seems to hesitate a good bit as soon as I punch it.

I checked for knock and there is none. The car feels great at all other time (even 90% throttle) and this only happens when I floor it.

Can someone point me in the right direction?

Thanks in advance,

J

PS - My setup:

Comptech SC/AC w/3.6" pulley
440cc injectors
stock FPR
stock map sensor (should not be an issue)
exhaust w/TP

What are your ARFs?

Since you have tune most of the map beside WOT, i assume the AFR and timing is right, check spark plugs, try .30 gap

If you leave the laptop connected while the engine is on, you can open A/F chart, timing, etc and it'll show you where you are on the chart so you can adjust accordingly.

This is a tuning issue and not mechanical however, so don't be worried per say

What do the logs show when you go WOT?

Hey guys...
Thanks for the input. I AFR's/timing look good (AFR's at partial throttle don't get above 12.5ish. I will do a quick WOT spurt today to see what the log says. To be honest, I'm still not very good at using the data logging software. I find it difficult to read the data.

Is there a way for me to post a log on here?

Thanks to everyone!

^ silly question, but have you calibrated your TPS?

I don't believe I have! Awe man...can someone explain how to do this?

THANK YOU!

It's pretty simple, just hook up your laptop to the ems. Open AEMpro, open the menus Configure/ECU setup/Set Throttle Range, and follow the instructions. You're basically telling your ecu what voltage equates to what throttle angle. Might be worth a shot...

Thanks man. I didn't think to do this. I bet this is my problem.
