Car - AE86

motor / part in question - 7age

problem - I have just swapped out a tired old 4age with a freshly built 7age, everything is done and the engine idles fine. As soon as you put your foot down it hits 2500rpm and losses power and drops down to 1500rpm and couldnt rev past 2500rpm. I replaced the MAP sensor which was suggested from a few people. Now the issue is still occruing however I can rev it past 2500rpm all the way upto 4000rpm(didnt go any higher as its a fresh rebuild with new cams)

I have also had the tps adjusted and removed map sensor all together still with the same result.

It has been suggested to do a ecu reset, which i will try on the weekend. Has anyone had a similar issue? or does anyone have any other suggestions what it might be.

Thanks
Az

Checked TDC? Its probably not anything to do with timing though as its idling fine. Just a suggestion

Yes we checked that and it was fine.
