Help Boosting Problems

[neil_jdmr]

Either way and I know you won\'t want this advice is £400 for a apex pfc and £250 for a map and it\'s all sorted. When I started out I tried for 9 months with loads of good suggestions but in the end it was the best money I spent.

As above, using a stock JDM ecu in the UK is just asking for trouble especially if you have a heavy right foot , get a stand alone ecu like the apexi or adaptronic and get it remapped.

Really? i take it thats a second hand PFC? Im in scotland, are there any good Tuners out this way?

And the only worry mate is if it doesnt solve the problem

^^^^what he said... i drove round for a year at 0.5 bar ...got an apexi and remap...0.8 bar woo hoo power!

[neil_jdmr]

If they are black it\'s running  rich but tbh a New set on for £40 solves that. What is your boost pattern 10-8-10psi is stock standard?

Then the tuner will switch the mapping session to a diag session....

either way cheaper than a rebuild mate....they dont like detonation...

It will be worth it in the end.

Where do yous find a set of plugs for them? my local motac didnt have them.

Well im not sure mate as i hit 0.7bar (10psi) and then fuel cut so dont know

Mazda Rotary Parts. On here bud...most normal motor factors dont have a clue when it comes to rotarys and parts will be costly.

Keep the faith cars are awesome....do your back ground reading...lots of stickies here.

[Sooperkent]

Any other ideas as to what i could check or do in the meantime?

Rats nest mate...uim off and check the vacuum pipes.

[Sooperkent]

After reading up a ton there - it seems as though my secondary injectors are possibly not working - hence it leaning out on second turbo and fuel cutting.

i will test them when i get a chance (aswell as replace all hose with fresh vacuum hose (just bought 10m of it) and get back to yous

[Sooperkent]

ok, so ran a positive and ground source to both secondary injectors - they are both clicking which means they should be working. Any other ideas?

[neil_jdmr]

Fuel pump possible  or wiring/relay.

[Sooperkent]

Already replaced plugs/fuel filter also going to replace fuel pump and sock on saturday - last resort is new injectors - after that only thing i could be is wiring loom.

Did the poor mans non sequential while we had the UIM off and now its not boosting at all - Boost leak is posible or i might not have done the poor mans nonseq right?

Haha endless rotary problems
