Hello Paul,
I thought that may be you can help me. When I tune jzx90 toyota chaser with power fc I have an interesting issue which I couldn’t solve. Issue is when I plug in tps sensor socket and make wide open throttle car bogs (like boost cut but off course its not a boost cut because no boost yet.) and when I plug off tps socket engine check light comes on but engine revs and boost comes on without any bog. On power fc commander vta1 is 0.4v at idle and at wot its around 4.1v. If you can advise some solutions to me I will be happy, may be I did something wrong but tps looks fine because voltage increase when throttle opened and check engine light goes of when I plug in the tps socket. Thank you in advance.
