ok thank u very much mate !!!

Thanks for the reply!!! I wanted to do this from the start when i was building the engine but unfortunately here in Cyprus there isn't any guy with such experience to do a job like this and the only way was to ship the head to another country which was very expensive.. So that is why the head doesn't have any work on it such as valves and porting and polishing... My question is if my dynograph looks similar with other 4E's with the same or close enough setup because i feel something is wrong with the mid range power... :/

Hi guys and greetings from Cyprus!! The setup of the car is a forged 4E with 5E cams and intake manifold with a VF30 turbo boosting around 25 psi. My question is how can i improve the mid range of the car without losing the top end power if its possible without the use of Nitrous??? Also the car has all the supporting mods and it runs with a standalone Adaptronic 420c Ecu!!! Thanks a lot in advance!! http://s1339.photobucket.com/user/sk-evo-s/media/280whp_zpsb1673476.jpg.html?o=0

Sorry mate didn't read all of that you stated you checked

Have you checked ignition timing ?? I had the same problem with my car and when i spoke with my tuner and studied the power graph he said that my problem at the mid-range rpm was the ignition timing ..

My friend @Chief Quimby i tried what you suggested to me and it had absolute success.... The problem now is isolated but with no such big resistor... We used 2 resistors 1 kohm each on the 2 signals at the ECU harness and worked brilliant... Now i can actually see at what RPMs the engine is also there aren't any spikes on the rev count any more and can actually make pulls whenever i want... Thanks a lot guys for the replies they really were very helpful!!!!

We highly suspected that it was the trigger but with one other distributor did the same thing ... Maybe both distributors that checked had problem because i dont know how it performed at a stock car. The ECU after i start the car reads the correct rpms... But for example when i make 2-3 pulls under load or drive the car for a long distance or put the launch control switch for 1-2 times the ECU reads 46000 rpms.. My tuner said it must be the trigger inside the distributor... My question is if it is a possible and easy way to isolate this problem or if i need to change in COP ignition because f

So there isn't any fault with the distributior it just wants this resistor ??

The problem came after the installation of the Standalone Ecu !!!

Hi guys and greetings from Cyprus!!! I went today to my tuner and plug my ECU to make some corrections on the rev-limiter and launch control and came with the problem that after a short time working the ECU reads very high RPMs and starts misbehave at both revlimiter , launch and at pulls under load.. My question is if this is a common problem with the distributor when running on Standalone ECUs or this maybe caused from the years so if i change a distributor will be fixed. Currently i am using a Adaptronic e420c ECU which is standalone ... Does anyone had the same problem before with s

thanks mate it didn't came in my mind i will check them ...

Hi guys and greetings from Cyprus!!! I come up with this problem within these few days and don't really know what to check or what is the cause ... My Ep91 Glanza V when i am trying to hit boost on every gear it starts to misfire.. This weird misfires come with a weird jump on the rev counter.. For example when i am at 4500 rpm and builts boost suddenly the rev counter jumps at 6000 rpm or 7500 rpm and it starts misfire... Also this happens in daylight BUT at nights it boosts normally as it should and that's why it drives me crazy. I changed distributor and re-gap the spark plugs. I

ok mate no problem!!!

This car is in Cyprus... On previous setup we went for a ride with the owner!!! This thing is crazy !!! The owner also has a Starlet EP82 and it was on similar setup as this Yaris , and he is one of the Starlet specialists in Cyprus..

Maybe is from the weather mate or maybe your wastegate has gone... On my car at first i thought it was from the cold but then i discovered i had a broken wastegate ... Hope i helped....
