Brilliant!
Thanks for this and l'm happy the values l'm using are close to ideal.
I will use 3.64v - 100 kpa as shown.

Re: AE86 MAP sensor values
The AEM ecu requires max and min voltages plus max and min pressures, it does not have a learning facility. I used a MAP enabled AE86 specific Freedom ecu to read the pressures and the AEM to show the voltages, the voltages are not affected by calibration changes. A Mityvac was used to obtain the va...

Does anyone know how often the stock ecu fires the injectors?
Ideally in engine degrees (over 720°) or distributor teeth.
My distributor has 24 ne teeth at 30° and 4 cam? teeth at
180°

What happens if you very slowly increase the power through the problem rpm area?
It may or may not be an acceleration correction problem.

Re: I have a built 7A motor. Need some advice
If the distributor has a pin holding the gear on, remove the pin and rotate the gear 180° on the distributor shaft
Re-fit distributor as normal.
Use a new roll pin to secure the gear.

Re: Wanting to replace Kelforf 193-C Camshafts
I'd not expect those things to make too much difference. In a way it is the standard cam followers that cause the compromise as these effectively limit the cam lift potential, any perfomance cam then has to rely on long duration to get the job done, it is the long duration that can cause driveabilit...

Re: Wanting to replace Kelforf 193-C Camshafts
Whilst l appreciate your post is about changing the cams it maybe possible to get closer to your requirements with careful tuning of camshafts and ecu. Having less overlap at TDC will help idle, retard inlet and advance exhaust cams to get less overlap. Cold and hot starts are all about ecu calibrat...

So l can't decide if l discovered something here. Timing decided to return to 0° btdc (effectively no signal to ecu) at cold start up. Because of the camshafts l unplugged the cold start injector. Once the csi was re-plugged ignition returned to normal. The 0°btdc seemed random but now, thinking abo...

Re: Question on machining costs
To be honest the only way l can see an issue with what they charged is if they didn't adhere reasonably closely to a written quote.
I don't know about the US but in the U.K there is a distinct legal difference between a quote and an estimate.

Re: Question on machining costs
5k$ does sound a lot for that work.
I'm in the U.K where this type of specialist work maybe less expensive, not sure.
I quoted Pounds Sterling but the exchange rate wouldn't make up that difference even if you allowed a 25% error
in actual cost.

Re: more suspension issues
Ideally you want the inner balljoint ball centres to be the same distance apart as the AE86 rack.
l would hazard a guess that the balljoint centres are the same distance apart as the track control arm pivot bolt centres.
I might try to measure that sometime.

Try always to use factory style crimps especially for repairs.
I use Male/Female narrow non-insulated bullet type connectors with heatshrink. Those 'orrid blue insulated squashy efforts are sent by the Devil!
Make sure any repair like this is taped into the loom for support.
