Prays for it not to rain

Well chris i never use the aem's anyway for mapping so no point me checking them but was just a general post worrying for other using them. As you said i always calibrate mine every week but then its in use every day

Glad your happy with car neil. The link ecu has the ability to have up to 5 inputs connected (plus model) for switches and then up to 10 aux output for wiring in like shift light, solenoids to control anything from TT setup to nitrous or water injection etc. In the future were gunna wire in the launch control, water injection and a shift light. The bit i liked about neil setup is the cost of it all. The link g3 is around about £400 cheaper than the aem ecu and that comes with its own map sensor and then for an extra £40 you can get the link boost solenoid so no need for any boost controllers as has 3d mapping for solenoid control and compensaton adjustments for AIT and Water temps. You then can wire in a switch or dial to control how much boost you want to run. In Neils case i put a switch in for high and low mode. No need for a DLI also I could go on and on but all that matters is neil is happy Look forward to tweaking it on the dyno as i was so surprised that a man the size of neil (6ft+ and over 18 stone) was such a wimp with the throttle pedal. When mapping at 1.3bar he kept getting abit nervous and letting off abit. Told him i need to get jamiep or homer behind wheel. Lova ya neil Please dont crush me

2.2bar on normal unleaded

Weather is looking good chaps just hope the dyno cell doesn't get too hot

Mr keef how you fancy doing your car on friday night then bud if your down this way?

I take it that is when your using a aem ecu? Thanks for your input, the exhaust clamp i use is modified so it actually sits right up in the exhaust for maximum flow. It also works on a venturi effect and have yet to find it read wrong but im sure a big exhaust leak would effect it. The problem is tho the aem wideband on one instance was reading 13:1 and the my innovate was reading 11.7:1. So that puts out that theory as no way it can get richer back there from exhaust leak etc. I would prefer as you say to use the down pipe method but i just dont have time to jack a car up and weld in or fit the sensor when mapping around europe. Like i said have tested my exhaust clamp lots with downpipe method and readings are always spot on. Maybe i just lucky and have mapped car with dogdy sensors but just slighty concerned me seeing on 3 cars now in last couple of monthes

Thanks wez but its the Uego which I'm commenting on

Tony you know I won't touch an aem so deffo can't be serial type. Don't forget tony I have a nice linkg3 here with your name on it wink wink

unfortunatly not ian have seen 2 now that have been way out in the past monthes as is pretty scary espically if there reading rich when its wrong and you lean it out. Do you use your own wideband for mapping ian or use a customers if in place?

Well the only aem gauge i have ever seen be close to my innovate was yours tony and a friends of jamiep's. But the rest i have looked at havn't even been close. A big difference. I never fit these for people and never use them if already fitted for when im mapping a car as have no faith in them. The switch on the back are for configuring output type but never touch them as dont use the wideband for mapping

Thanks J that helps as at least i know it can be done Well have searched the Aempower forum and no one knows of anything but be very interested to know not for my sake but others.

Does anyone know if you can recalibrate these units as have only seen one unit that is even close to my innovate wideband or my Vems wideband at present. All others are just way out Mapped a car on saturday that had one fitted and was reading 13:1 on AEM and then on my innovate i was seeing 11.7:1 (aem was in downpipe and innovate was using exhaust clamp) I was so confused i used a brand new sensor and free air calibrated and got exactly the same figures as before on innovate and vems Another example supra i have mapped i see 11.5:1 on my innovate wideband and then their aem shows 10:1. And theres mores So is there anyway to recalibrate these gauges or are they just another flashing paper weight

I have got a ironing board for sale if that help andy

Morning mate Yes got your PM thanks I guess have a word with b'have (charlie) as he has both a phr turbo'd supra and a gt4088 one. Lucky git. I remember when mapping he said 0.9bar on the gt4088 felt like 1.2-1.3 on the phr 1

Im 98% sure neil will be there homer as he said 100% yesterday but things could of change after all the TF hassle etc Ryan

Now all thats left is twisting his arm to get rid of the AEM

Hi suprawomen What ecu are u running Ryan

I'm looking forward to seeing homers car next week ever since his crank was on its way out it seems to have lost a fair bit of power. My thoughts at present is either the base timing has changed from where there is problem with crank senor due to when the pulley was loose . This will be checked with timing light as can lock timing ref on powerfc. Also going to monitor the pulses through link ecu and see if there are any errors on crank signals or cam. Then fit new 2.5bar map sensor and tweak on road.

Hi Graham not a problem Yes it is possiable to run lower boost in the selected gears but it depends on what is controlling the boost solenoid if it is the link ecu then yes but i will need to run a speedo output into the digital input on the ecu. (if it not already done) This will probably have to be done after the rolling road day tho. Please pm me to discuss more Ryan

Hey guys Time slots looks good to me only thing i would ask if could be changed is that big blue was the the 11-12 time slot as will be tweaking his car also on dyno as is another one of my customers and takes time between all the cars i map to plug in and wire up det cans Homers will only need a tweak as will be finished mostly next week when new map sensor is fitted and i can fixing ignition timing and lean out as something has changed since crank pulley problem. Grahamc want me to check over his map from thor on dyno and maybe tweak depending on how much is needed. I will then need to spend some time sorting some other small problems he has. Then its tweak big blues car if it can be moved Then i will be looking at mr keefs car on the road and mapping for uk fuel this shouldn't take long if it has a decent map on it but i have seen a few cars from japan recently just running base map. Then its tweak on dyno

Hi Bondango The system uses some bosch sensor as they are broadband sensors and dont just listen to a certain freq like standard toyota ones. I have not installed a V3.3 ecu yet but the guys at vems are waiting to send one to me soon for some testing but i feel its abit too early in devolpment at present to match other ecus like the Link g3. The link g3 would be a good buy for the 7mgte crowd. I have just got a few over from NZ and could certainly help with fitting etc

The phormula unit has just been tested and developed with the sr20 engine but that does not mean it wont work with other engines. Each engine has a certain freq range where det is most present with the sr20 it seems its between 6-9 kHz but tbh that where it is on most engine. I know the 2jzgte and 3sgte knock sensors only listen for freq range 6 kHz. See the graph below with shows an example of how det changes in different bore sizes. (mode 1) http://www.vems.co.uk/VEMSUserManual/knockfrequencycurves.jpg There are some formulas to work out freq range but i find this chart is always 98% right. But i just keep the freq open between 6 and 8 kHz on my det system to have a wider range

Ian i Have a spare bosch knock sensor if you want to test it with your knock lite
