ok so i got my rx7 running and i take it for its first test drive it was running rely odd so i looked at the timing and it was off so i adjust it, this test drive gets me to boost at 5psi then i shifted and tryed to boost, if i hit the gas to much it will shutter like its hitting boost limiter, if i shut the car off to powercycle the ecu i can hit boost. the odd things comes when i can hit boost in 3 or 4 gears sometimes and it will pull so fast and so hard at half throttle its a new rebuilt engine so i dont want to floor it and risk breaking something, its not the tps as i noticed the JDM engine did not come with a TPS so i was running it with out a tps now that i do have a tps its the same story, tps just fixed the hesitation at a steady throttle. i was missing a "pill" to ristrick the flow of air to the map so i build one as per mazda specs and still the same problem, im confused, some times it will run just fine for a while so i part it, next day or week i come back to the car and same problem. dose any on live near london that has a working S5 turbo map sensor and or a S5 turbo Maf i could use to try, im getting married next may and i cant offord to spend 400$ on a maf that might not be the problem, nor can i offord to buy a afm that might not fix the problem as well.

thanks for your help and any input
PS i did search and tryed all the tricks still no go, just like many other ppl with Tii

 

well hers an up date i fixed the cracked wires to the cas and after work i had sameer come and help me tonight at 1am lol, we took for a ride and reset the timing of the leading and trailing, then we took it for a test drive same thing 3 gears then no more boosting. i shut it down fire it back up and went to a culdasac and did a donuts so i could play with the boost and it stayed in boost while i was sort of drifting, then as i pulled and made it hold its boost steady it stooped hitting boost. we left it do that so we could do some testing, as once it in this mode even at reving it up at idle will make it not hit boost at all as well, so we unplugged the temp sensor same thing so we plugged it back in. next we unplugged the map sensor vacuum line same thing?.... next we unplugged the 3 wire plug to the map sensor SAME THING STILL CANT GET IT TO HIT BOOST??..... well, only one thing left was the afm. we we unplugged it with the car running, and it chaged the way the car was responding, i so finaly something makes this disapear now we all know the car wont take all the gas i can give it with the afm disconnected but what shocked me was that when we reconnected the afm with the car still running i was able to hit boost once more before it went back in that mode, we we disconnected it once more to see if it would let me boost but it did not,..... so we take it out for an other test drive after shutting down the car, and i got 5 gears of boost i thought it was fixed then no more boost still have the same prob im relay thinking its the bad AFM NOW,
