S300 causing limp mode?
S300 causing limp mode?
I have an issue with my vehicle not revving above 1500 rpm's and this only started after fixing another issue ( Cel light, idle surging and unable to read the CEL from Smanager). I have no CELs and no loose connections that I can see but the engine will not allow me to rev above 1500 rpm's while in neutral or driving. It acts like it's in limp mode. The only reason I'm posting it here is because it started when the S300 was properly plugged in. Also the car did not have the issue with revving while the other problems were happening.

Post the calibraiotn that it is running on now as well as a datalog showing the problem.

Forgive my noobness but how do I post those to a forum?

I'll get that ASAP but for reference it's just a simple N/A H22 with bolt-ons.

This is the calibration that has been running the car
This is the datalog taken of the car idling and me revving it.

Can't see anything weird apart from the battery voltage dropping at times.
Create a new calibration, then import the tables from you old calibration, copy over the injector and VTEC settings, see if that works.

Alright, once my tuner tells me how to do it I'll try that.
As an update I wanted to list some observations I've made. With the S300 plugged in incorrectly the car had the surging idle and other issues listed in my other thread but it had no rpm limit and I could drive the car normally. The 4 pins nearest the long side of the ecu were the ones that were not plugged in. Once correctly plugged in I had a steady idle and the other issues were fixed but I was limited to 1900 rpms and there was a hard cutoff like a rev limiter. I found out that the VTEC solenoid wire had come out from the plug and that was originally limiting me to 1500 rpms. Maybe this will help narrow the issue down.

Re: S300 causing limp mode?
What is the serial number that is on the s300 board inside the ECU?
From Help, About, what is the version of software you are using?
Who socketed this ECU?

Re: S300 causing limp mode?
my serial # is 34385, Currently running software 2.5.6.0 and the ECU was socketed by HA motorsports (who also provided the new ECU).
Re: S300 causing limp mode?
Try closing the SManager software completely, then reopening it and then go to new calibration and upload a fresh basemap and see if the car runs properly then.
Re: S300 causing limp mode?
Seems to have fixed the issue. Just going to check if it does it with my stock calibration and if so I'll work off the base map (I'm not far from stock anyways).
